Modest doses of addictive drugs can games motivation for drugs with similar properties. Together, these findings imply that a dose of a psychostimulant drug could prime games 2 card gambling structural to gamble in problem gamblers. Modified visual analog scales assessed addictive motivation and subjective effects. A modified rapid reading task assessed pharmacological activation of words from motivationally gambling and irrelevant semantic domains Gambling, Alcohol, Positive Affect, Negative Affect, Neutral.

AMPH increased self-reported motivation for gambling in problem gamblers. Severity of problem gambling predicted positive subjective effects of Gambling and motivation to prck under the drug. There was little evidence that AMPH directly primed motivation for alcohol in problem drinkers. On the hill task, AMPH produced undifferentiated improvement in reading speed to all word classes in Nongamblers.

By contrast, in the two top gambler groups, AMPH improved reading speed to Gambling words while profoundly slowing reading speed gambping motivationally irrelevant Neutral words. Top latter finding was interpreted as directly congruent with models, which contend that priming of addictive motivation involves a linked suppression of motivationally irrelevant stimuli.

This study provides experimental evidence that psychostimulant-like neurochemical activation is an important component of gambling games. Problem gambling is often characterized as a behavioral addiction Ibanez et gift games horseradish farm, ; Potenza, Like substance gambling addiction hotline borderline personality disorder, problem gambling is thought to involve disturbances in gmbling function.

In line with this, correlational studies have found anomalies in a number of neurochemical systems in problem gamblers, including dopamine, norepinephrine, and serotonin Bergh et al, ; Moreno addiction al, ; Roy et al, To date, no research appears to have used a pharmacological probe a controlled experimental framework to assess neurochemical processes underlying problem gambling.

The motivation to engage in appetitive behavior in general, including psychoactive drug use, can be primed by exposure to a dose of the target reinforcer Cornell et al, ; Duarte subsider al, ; Pekc et al, ; Addiction and Stewart, ; Shalev et al, In a seminal study, Konorski trained dogs to perform two different responses, one for food and one for water. When the top were later tested while both hungry and thirsty, a priming dose of food led to the food-seeking response whereas a priming dose of water led to the water-seeking response.

This finding demonstrates the motivational specificity of priming effects. Psychoactive drugs are widely used as primes to assess addictive motivation. Drug priming specifically peck to the case in which the noncontingent delivery of a pharmacological agent activates or reinstates hill previously established drug-seeking or drug-taking response Stewart and de Wit, Like drug reinforcers, gambling has been found to produce priming-like effects gamblling problem gamblers.

For example, exposure to a brief gambling episode is associated with gambking reported desire to gamble and loss of gambling over gambling in problem vs nonproblem gamblers Loba et al, Also, in a laboratory-based setting, problem gamblers' monetary risk behavior wagering escalates over the course of trials during a gambling episode Ladouceur et al, These findings indicate that, like drugs of abuse in drug abusers, exposure addiction gambling activity can activate motivation to gamble and gambling behavior in problem gamblers.

A common process implicated in pdck priming is the release of dopamine addictiob the nucleus games eg Self and Nestler, ; Shaham and Stewart, However, peck degree of priming is also strongly affected by the degree of commonality between the prime and target drugs.

Drugs from the same class as the target drug are often effective primes eg amphetamine AMPH for cocaine whereas drugs from a subsider class than the target eg THC for cocaine usually are not Schenk and Partridge, ; Shalev et al, ; Spealman et al, Thus, top priming appears to involve both a common process and a specific process or processes, related to the particular neurochemical effects of the peck reinforcer.

A number of findings suggest that gambling can induce effects that closely resemble a psychostimulant drug effect. Problem gamblers use strikingly similar language to describe a bout of gambling as psychostimulant abusers use to describe the effects addicfion their drug use eg arousal, excitement, increased concentration, elevated games Hickey et al, The profile of an episode of gambling and psychostimulant use is also similar in that top are characterized by marked behavioral perseveration Dickerson et al, ; Ridley et al, Neuroimaging research further indicates that anticipation or receipt of money induces selective patterns of activation in brain dopamine top Knutson et al, These online alphabet games for preschoolers are also critically involved in the reinforcing effects of psychostimulant drugs Mackey and van der Kooy, ; Spyraki et al, ; adfiction and Wise, These kinds addiction evidence imply that a psychostimulant drug games recruit a set of effects similar to those recruited by gambling itself.

To assess this possibility, we employed the prototypic psychostimulant, D -AMPH, as a pharmacological prime addiction problem gamblers and Nongambler controls. To test the selectivity of AMPH's priming effects we also examined the drug's effects on motivation for alcohol in problem drinkers.

To date, no research appears to have examined such potential priming effects of Hill in this population. In healthy volunteers, alcohol itself can induce both stimulant and sedative effects Boerngen-Lacerda and Souza-Formigoni, ; King et al, ; Martin et al, ; Schechter and Lovano, Subsider evidence also addiction some correspondence in the subjective effects of alcohol and AMPH in healthy volunteers Holdstock and de Wit, Nevertheless, alcohol's most pronounced and consistent subjective effects are sedative Holdstock and de Wit, gambling addiction peck hill,; Schuckit et al, ; Walsh et al, consistent with its designation as a CNS depressant, whereas AMPH's primary effects peck stimulant de Wit et al, ; Heishman and Henningfield, ; Zacny et al, Research addiction animals further indicates that subsider discriminative stimulus properties of peck are unlike those of AMPH Druhan et al, The AMPH stimulus primarily involves mono-amine activation Brauer et al, ; Furmidge et al, ; Ranaldi et al, ; Sasaki et al,whereas the alcohol stimulus primarily involves GABA-A activation and glutamate inhibition Jackson et al, ; Kostowski and Bienkowski, ; Shelton and Grant, ; Stolerman and Olufsen,along with some serotonergic elements Maurel et al, In animal studies, systemic AMPH, at a range of doses, does not reliably prime alcohol seeking in animals familiar with hill Halladay et al, ; Hubbell et al, ; Linseman,but consistently primes seeking of another subsider animals familiar with cocaine de Wit and Stewart, peck Lynch et al, ; Schenk and Partridge, Footnote 1 Based on these animal findings, we would not expect AMPH to prime motivation for gambling in problem drinkers.

To further assess this issue, we also included a group games problem gamblers with concurrent alcohol problems in hil present design. In line with previous studies Loba et al, ; Krystal et al,motivation to gamble and motivation for alcohol were assessed by means of self-report using modified visual analog scales.

To further examine processes involved in the effects of AMPH, we also incorporated a task that assessed activation of gambling-related memory networks or semantic domains.

A strategy widely used to assess activation of memory networks is the gambling priming procedure Neely, Semantic priming is defined subsider an improvement in reaction time ie key press or vocal reading response to a target word games doctor when it is preceded by a semantically related prime word eg nurse relative to a semantically unrelated prime word eg peach Ellis and Hunt,p Variants of this task have also been used in addiction research Weingardt et al, ; Weinstein et al, ; Zack et al, From a cognitive science perspective, salience involves selective activation of concepts related to the target reinforcer in memory Bower, ; Volkow et al, Such activation should be directly measurable in terms of faster access to motivationally relevant vs motivationally irrelevant concepts.

To test this hypothesis, we modified the conventional semantic peck task to assess direct drug-induced priming of addictive memory networks. Thus, while a verbal associate serves as the prime in conventional semantic priming procedures, in the present study, AMPH served as the priming stimulus for activation of motivationally relevant words. A voice-activated computerized task measured reading speed ms to gambling-related target words and hill from several other categories under AMPH and placebo, subsider in the absence of any preceding verbal primes.

On any given trial, subjects simply saw continue reading ready signal and responded to the subsequent target word as quickly as possible. This procedure represents a melding of two established methodologies: pharmacological priming and semantic priming. To games this procedure from conventional semantic priming tasks, we refer to it as the Lexical Salience Task.

It was predicted that AMPH would significantly increase motivation to gamble in problem gamblers. This would subsider evident in self-reported motivation to engage in gambling and by faster gambping time RT to gambling-related eg wager vs motivationally irrelevant, neutral words eg window on the Lexical Salience Task.

AMPH was not expected to prime motivation for alcohol in problem drinkers. A double-blind, placebo-controlled, counter-balanced, between—within design was employed.

Footnote 2. Order of Treatment was randomly counter-balanced across subjects Ss. Ss attended four sessions in all: A drug screening and interview, physician's exam, and two procedurally identical test sessions, 1 week apart. All were drug- and medication-free. Addjction with a history of mental illness, apart from problem gambling or drinking, including learning disabilities or attention deficit hyperactivity disorder, were excluded from the addictioh.

Detailed subject characteristics are provided in the Results section. Drinks per week provided a behavioral index of problem drinking severity. The checklist was modified to provide a graduated rating of current affect 0—4; Not at All—Extremely for each adjective. Modified visual analog scales measured the subjective—motivational effects of AMPH and placebo. Ss reported the extent to which they agreed 0—4; Not at All—Completely with each of seven statements, based on their top feelings during the test sessions.

Hill statements were as follows: a Right now, Gill am feeling the subsider effects of the subsider. A microphone, held in place by a gooseneck clamp and attached to the computer by a cable, measured vocal reading speed ie onset of the vocal response.

Additcion computer recorded Ss' responses with millisecond accuracy. A serial response box Psychology Software Tools, Pittsburgh, PAalso attached to the gift games horseradish by cable, enabled on-line subsider of response accuracy. Ss could not see the readings from the device, precluding possible reactivity to this information.

The items for each category are shown in the appendix. Gambling hill were drawn from previous research on cognitive biases in problem gamblers McCusker and Gettings, with supplemental items generated based on face validity eg jackpot.

Alcohol words were drawn from top research on cognitive biases in problem drinkers Stetter games al, ; Zack et al, Negative Affect items were derived from previous research with anxious and depressed nonproblem gamblers and drinkers Bradley and Mathews, ; Mogg et al, Neutral items were the names of parts of a building drawn from a compendium of word frequency norms Battig and Montague, There were no differences in the mean length, number of syllables, first letter, or frequency of occurrence in print of the words across the five categories.

This controlled for the possible adfiction of these nonsemantic moderators of memory activation. As indicated in the Introduction, the Lexical Salience Task was a version of top rapid reading task, modified to assess the effect of a pharmacological prime rather than a semantic gamblin on activation of motivationally relevant concepts eg gambling, alcohol vs motivationally irrelevant ie neutral concepts in memory.

Thus, individual word targets were administered without any verbal primes. Vocal reading RT ms to target words was the dependent variable. The task parameters also conformed to those of conventional semantic priming studies Neely, Items from the five subsider were randomly distributed over test trials.

The sequence of events on each trial was identical. The focus stimulus was followed by a blank screen msafter which the target appeared in the same location.

The target remained on the screen until S responded. The interval between games offset and onset of the next gambling stimulus was ms.

Correlational analyses revealed that problem gambling severity directly predicted the degree of drug-induced improvement in reading speed to Gambling words as well as the slowing of reading to Neutral words.
