Changes in cue-induced, prefrontal cortex activity with video-game play

Brain responses, particularly within the orbitofrontal and cingulate cortices, to Internet video-game cues in college students are similar to those observed in patients with substance dependence in response to the substance-related cues. In this study, we report changes in brain activity between baseline and following 6 weeks of Internet video-game play. We hypothesized that subjects with high levels of self-reported craving for Internet video-game play would be associated with increased activity in the prefrontal cortex, particularly the orbitofrontal and anterior cingulate cortex. Twenty-one healthy university students were recruited. At baseline and after a 6-week period of Internet video-game play, brain activity during presentation of video-game cues was assessed using 3T blood oxygen level dependent functional magnetic resonance imaging. Craving for Internet video-game play was assessed by self-report on a 7-point visual analogue scale following cue presentation. During a standardized 6-week video-game play period, brain activity in the anterior cingulate and orbitofrontal cortex of the excessive Internet game-playing group (EIGP) increased in response to Internet video-game cues. In contrast, activity observed in the general player group (GP) was not changed or decreased. In addition, the change of craving for Internet video games was positively correlated with the change in activity of the anterior cingulate in all subjects. These changes in frontal-lobe activity with extended video-game play may be similar to those observed during the early stages of addiction.     

fMRI responses to Jung's Word Association Test: implications for theory,treatment and research

Jung's Word Association Test was performed under fMRI conditions by 12 normal subjects. Pooled complexed responses were contrasted against pooled neutral ones. The fMRI activation pattern of this generic ‘complexed response’ was very strong (corrected Z scores ranging from 4.90 to 5.69). The activation pattern in each hemisphere includes mirror neurone areas that track ‘otherness’ (perspectival empathy), anterior insula (both self‐awareness and emotional empathy), and cingulated gyrus (self‐awareness and conflict‐monitoring). These are the sites described by Siegel and colleagues as the ‘resonance circuitry’ in the brain which is central to mindfulness (awareness of self) and empathy (sense of the other), negotiations between self awareness and the ‘internal other’. But there is also an interhemispheric dialogue. Within 3 seconds, the left hemisphere over‐rides the right (at least in our normal subjects). Mindfulness and empathy are central to good psychotherapy, and complexes can be windows of opportunity if left‐brain hegemony is resisted. This study sets foundations for further research: (i) QEEG studies (with their finer temporal resolution) of complexed responses in normal subjects (ii) QEEG and fMRI studies of complexed responses in other conditions, like schizophrenia, PTSD, disorders of self organization.     

Explaining Addiction: How Far Does the Reward Account of Motivation Take Us?

ABSTRACT

Choice theorists such as George Ainslie and Gene Heyman argue that the drug-seeking behaviour of addicts is best understood in the same terms that explain everyday choices. Everyday choices, they claim, aim to maximise the reward from available incentives. Continuing drug-use is, therefore, what addicts most want given the incentives they are aware of but they will change their behaviour if and when better incentives become available. This model might explain many typical cases of addiction, but there are hard cases that pose a problem. In these hard cases the addicted individual does not cease using drugs in the face of consequences that are so adverse it is implausible that they are unaware of more rewarding paths of action. These cases force the choice theorist into a dilemma: either these addicts’ drug use does not count as action and so is best described by a neurobiological model, or reference to ‘reward’ in these cases means merely ‘motivated’ and so provides no explanatory power. We propose a different model of motivation that takes self-conception into account. We show how that can better explain the hard cases of addiction and also inform our understanding of recovery and self-control.     

Addressing Anger,Stress, and Alcohol-Related Difficulties in the Military: An ACT Intervention

The use of alcohol to manage emotion is a common technique seen in military service personnel, the implication of which is evident in the relationship between alcohol misuse and mood disorders. However, investigations into transdiagnostic treatments aimed at addressing the common underlying processes to these problems in military personnel are lacking. The present study aimed to investigate the efficacy of a real-world Acceptance and Commitment Therapy (ACT)-based intervention undergone by 262 military personnel. A quasi-experimental prepost design was employed (interim 1 month postintervention) with a waitlist control group utilized to compare differences over time between those who promptly completed the week-long intervention course and the delayed waitlist participants. In line with predictions, the intervention group showed greater improvement (cf. preintervention waitlist group) in emotion management, and greater reductions in levels of alcohol consumption, aggression, anxiety, stress, and perceptions of others being responsible for their circumstances. No significant differences were found in the comparison of both groups’ 1-month postintervention results (i.e., both groups evidenced similar improvements); suggesting having to wait to start the course had little effect on its impact. The results suggest the course holds promise for helping military service personnel improve a range of psychosocial outcomes. Further testing with a more rigorous methodology is recommended, as is using a more proactive approach in the promotion and implementation of future courses.     

Goal Internalization and Outcome Expectancy in Adolescent Anxiety

Anxiety has been conceptualized in terms of increased avoidance motivation and higher expectancies of undesirable outcomes. However, anxiety research has hitherto not examined an important qualitative aspect of motivation: the degree to which reasons for goal pursuit are experienced as controlling and originating outside the core self. We asked 70 adolescents (34 boys, 36 girls; aged 16–18 years) to list their important approach and avoidance goals, and rate the extent to which they pursued each goal for intrinsic, identified, introjected and external reasons. Participants also rated goal importance, expectancies for goal outcomes, and completed an anxious symptom measure. Broadly in line with predictions, anxiety was significantly associated with introjected reasons for pursuing approach goals and external reasons for pursuing avoidance goals but not with autonomous reasons for goal pursuit. As predicted, anxiety was significantly associated with heightened expectancies of undesirable avoidance goal outcomes, but not with expectancies for desirable approach goal outcomes. Results suggest that the salient role of avoidance-based motivation in anxiety extends to introjected reasons underlying approach goal pursuit. Our findings point to the theoretical and clinical importance of addressing controlled reasons for goal pursuit in adolescent anxiety.     

Personality Factors,Family Structure,and Sex of Drawn Figure on the Draw-A-Person Test

One hundred seventy-four youthful psychiatric inpatients were given the Draw-A-Person Test (DAP) as part of an assessment battery. Sex of person drawn was compared to subject's sex, Achenbach aggression and delinquency scores, and scores on Children's Inventory of Anger and Nowicki-Strickland Locus of Control Scale. The sex of the person drawn was also compared to family composition, specifically whether or not the child came from an intact family with both a male and female parent or role model. Results support drawing of a same-sexed individual as normative, regardless of age or sex. Adolescent girls and young boys were the only groups that differed significantly from this norm. Personality measures and family composition were not significantly related to the tendency to draw same versus opposite sex.     

Exploring the Relationships Among Multicultural Training Experiences and Attitudes Toward Diversity Among Counseling Students

The authors surveyed a national sample of master's‐level counseling students regarding their multicultural training experiences and their attitudes toward racial diversity and gender equity (see G. L. Dickson & D. A. Jepsen, 2007). Hierarchical regression models showed that student perceptions of program cultural ambience predicted positive cognitive attitudes toward racial diversity. Participatory instructional strategies predicted positive affective attitudes toward racial diversity. Los autores entrevistaron a una muestra nacional de estudiantes de Master en programas de consejería en relación a sus experiencias en formación multicultural y sus actitudes hacia la diversidad racial y la igualdad de sexo (ver G. L. Dickson & D. A. Jepsen, 2007). Los modelos de regresión jerárquica mostraron que las percepciones de los estudiantes de la atmósfera cultural en sus programas predijeron actitudes cognitivas positivas hacia la diversidad racial. Las estrategias didácticas participativas predijeron actitudes afectivas positivas hacia la diversidad racial.     

The effect of overlearning on long‐term retention

Once material has been learned to a criterion of one perfect trial, further study within the same session constitutes overlearning. Although overlearning is a popular learning strategy, its effect on long‐term retention is unclear. In two experiments presented here, 218 college students learned geography facts (Experiment 1) or word definitions (Experiment 2). The degree of learning was manipulated and measured via multiple test‐with‐feedback trials, and participants returned for a final cued recall test between 1 and 9 weeks later. The overlearners recalled far more than the low learners at the 1‐week test, but this difference decreased dramatically thereafter. These data suggest that overlearning (and its concomitant demand for additional study time) is an inefficient strategy for learning material for meaningfully long periods of time.

Mothers continuing bonds and ambivalence to personal mortality after the death of their child--an interpretative phenomenological analysis

The main objective of this study was to identify how bereaved mothers describe their coping strategies in their own words. The literature on parental bereavement is sparse, and the present study aims to add to existing knowledge by eliciting the mothers' experiences covering a wide range of child ages including infants, younger children and adults. Semi-structured interviews were held with 13 bereaved mothers in the UK. Causes of death include accident, illness and suicide. The methodological approach was interpretative phenomenological analysis (IPA). This article reports two inter-related recurrent themes: (1) Continuing the bond with the deceased child and (2) Ambivalence to personal mortality. Participants reported that the relationship with their child was continued in a variety of ways, from tending to the grave and the child's remains, through linking objects or by establishing a symbolic representation of the child within their daily lives. All mothers talked openly about their own mortality, either demonstrating ambivalence about their own death, or expressing clear suicidal ideation. Death was seen as a release from living with the pain of loss. The presence of surviving siblings appeared to moderate suicidal ideation, but mothers expressed concerns about their ability to care adequately for other family members during times of intense grief.
