REVIEW OF HEYMAN'S ADDICTION: A DISORDER OF CHOICE

Gene Heyman's Addiction: A Disorder of Choice (2009) advances the important, albeit controversial, view that addiction is not a chronic, relapsing brain disease, but instead is an example of typical everyday choice that is both voluntary and self‐destructive. This review highlights Heyman's arguments for conceptualizing addiction as choice and discusses the utility of the treatment implications that are derived from the melioration model in which Heyman frames addiction. Self‐control and behavioral economics are presented as additional complementary frameworks for understanding addiction as choice, from which pragmatic, evidence‐based treatments for addiction (e.g., contingency management) might more easily be derived.     

Further analysis of variables that affect self-control with aversive events

The purpose of this study was to examine variables that affect self-control in the context of academic task completion by elementary school children with autism. In the baseline assessment of Study 1, mathematics problem completion was shown to be an aversive event, and sensitivity to task magnitude, task difficulty, and delay to task completion were measured. The effects of manipulating values of those parameters on self-control then were assessed. For all participants, self-control increased as a function of one or more changes in task parameter values. In Study 2, the effects of a commitment response on self-control was assessed. Results indicated that for all participants, levels of self-control were higher when the opportunity to commit to the immediate aversive event was available.     

COMPUTER‐ASSISTED MEASUREMENT OF WOUND SIZE ASSOCIATED WITH SELF‐INJURIOUS BEHAVIOR

We evaluated an inexpensive, efficient, and noninvasive technique for measuring tissue damage produced by self‐injurious behavior (SIB). The technique involved computerized measurement of wound surface area (WSA) based on digital photographs. In Study 1, we compared photographic measurement to a more commonly used procedure, transparency measurement, in estimating WSA of 20 wound models. Results showed that both methods were reliable and that there was a high degree of correspondence between the 2 sets of measures. In Study 2, we compared photographic WSA measures to direct‐observation measures in documenting changes over time in the SIB exhibited by a woman with Prader‐Willi syndrome. Results showed that increases and decreases in observed SIB during baseline and treatment conditions corresponded with changes in WSA measures, indicating that the computer‐assisted photographic technique may be useful as a corroborative measure or as a primary measure when direct observation of SIB is not feasible.     

Effects of text messaged self-monitoring on class attendance and punctuality of at-risk college student athletes

This study examined the effects of text messaging class arrival to an academic counselor on the attendance and punctuality of 4 college student athletes. Each participant had a history of class tardiness and was considered to be at risk for academic failure. Class attendance and punctuality improved for all participants.     

Concurrent-chains schedules as a method to study choice between alcohol-associated conditioned reinforcers

An extensive body of research using concurrent-chains schedules of reinforcement has shown that choice for one of two differentially valued food-associated stimuli is dependent upon the overall temporal context in which those stimuli are embedded. The present experiments examined whether the concurrent chains procedure was useful for the study of behavior maintained by alcohol and alcohol-associated stimuli. In Experiment 1, rats responded on concurrent-chains schedules with equal variable-interval (VI) 10-s schedules in the initial links. Across conditions, fixed-interval schedules in the terminal links were varied to yield 1∶1, 9∶1, and 1∶9 ratios of alcohol delivery. Initial-link response rates reflected changes in terminal-link schedules, with greater relative responding in the rich terminal link. In Experiment 2, terminal-link schedules remained constant with a 9∶1 ratio of alcohol delivery rates while the length of two equal duration initial-link schedules was varied. Preference for the rich terminal link was less extreme when initial links were longer (i.e., the initial-link effect), as has been previously reported with food reinforcers. This result suggests that the conditioned reinforcing value of an alcohol-associated stimulus depends on the temporal context in which it is embedded. The concurrent-chains procedure and quantitative models of concurrent chains performance may provide a useful framework within which to study how contextual variables modulate preference for drug-associated conditioned reinforcers.     

Links between self-reported and laboratory behavioral impulsivity

Havik, M., Jakobson, A., Tamm, M., Paaver, M., Konstabel, K., Uusberg, A., Allik, J., Ööpik, V. & Kreegipuu, K. (2012). Links between self‐reported and laboratory behavioral impulsivity. Scandinavian Journal of Psychology 53, 216–223. A major problem in the research considering impulsivity is the lack of mutual understanding on how to measure and define impulsivity. Our study examined the relationship between self‐reported impulsivity, behavioral excitatory and inhibitory processes and time perception. Impulsivity – fast, premature, thoughtless or disinhibited behavior – was assessed in 58 normal, healthy participants (30 men, mean age 21.9 years). Self‐reported impulsivity as measured by Adaptive and Maladaptive Impulsivity Scale (AMIS) and behavioral excitatory and inhibitory processes as measured by Stop Signal Task were not directly related. Time perception, measured by the retrospective Time Estimation Task, was related to both. The length of the perceived time interval was positively correlated to AMIS Disinhibition subscale and negatively to several Stop Signal Task parameters. The longer subjects perceived the duration to last, the higher was their score on Disinhibition scale and the faster were their reactive responses in the Stop Signal Task. In summary our findings support the idea of cognitive tempo as a possible mechanism underlying impulsive behavior.     

Self‐esteem and emotional health in adolescents – gender and age as potential moderators

Moksnes, U. K. & Espnes, G. A. (2012). Self‐esteem and emotional health in adolescents – gender and age as a potential moderators. Scandinavian Journal of Psychology 53, 483–489. The present paper investigates possible gender and age differences on emotional states (depression and anxiety) and self‐esteem as well as the association between self‐esteem and emotional states. The cross‐sectional sectional sample consists of 1,209 adolescents 13–18 years from public elementary and secondary schools in mid‐Norway. The results showed that girls reported higher scores on state anxiety and state depression, whereas boys consistently scored higher on self‐esteem in all age groups. Self‐esteem was strongly and inversely associated with both state depression and state anxiety. An interaction effect of gender by self‐esteem was found on state depression, where the association was stronger for girls than for boys. The associations found give support for the positive role of self‐esteem in relation to adolescents’ emotional health and well‐being.     

The self and the passions

Jane McIntyre's authoritative presentation of the changes Hume makes in the Second Enquiry and the Dissertation on the Passions to the role of sympathy show that he has there left behind the centrality of the idea of the self in the Treatise, and made his philosophy less systematic but more comprehensive.     

Locus of control as a contributing factor in the relation between self-perception and adolescent aggression

Researchers continue to debate the role of self-esteem in aggression, but research has shown a consistent association between narcissism and aggression in adults and adolescents [e.g., Barry et al., 2007; Bushman and Baumeister, 1998; Stucke, 2007]. The primary aim of the current study was to examine whether locus of control (LOC) moderated the relation between self-perception variables (i.e., self-esteem and narcissism) and aggression in adolescents. Participants were 174 youth (145 males, 26 females) between the ages of 16 and 19 who were enrolled in a voluntary residential program for youth who have dropped out of school. The results showed that LOC moderated the association between self-esteem and aggression such that low self-esteem was associated with higher levels of aggression for individuals with an external LOC. Contrary to expectations, LOC failed to moderate the narcissism-aggression relation. The implications of this study for understanding how self-perception is related to adolescent aggression are discussed.     

Evaluation of a Combined Cognitive Behavioural Therapy and Interpersonal Process Group in the Psychotherapy Training of Clinical Psychologists

It is now widely acknowledged that both content and process elements of psychotherapy play a part in client treatment outcomes. Despite this, there are pressures on Australian clinical psychology training programs to teach evidence‐based approaches in a relatively short time frame. Producing clinical psychology graduates who have an adequate level of competence in evidence‐based practice and meeting the demands of professional accreditation requirements can mean that less time is available to teach the process elements of psychotherapy. The aim of this study was to conduct a preliminary evaluation of a clinical psychology psychotherapy training program that combines an interpersonal process group with a cognitive behavioural therapy training model that incorporates self‐reflection and self‐practice. Eleven participants who participated in the training in 2008 completed the Counseling Self‐Estimate Inventory at pre‐ and post‐training. Significant improvements on the majority of the subscales of this inventory were found. A separate sample of nine trainees and clinical psychology registrars who also previously completed the program attended individual interviews in 2010 aimed at gaining their perspective regarding various aspects of the program. Self‐practice of cognitive behavioural therapy techniques was found to be important in the identification and management of trainees’ own core beliefs, and to their appreciation of how challenging this process may be for clients. The interpersonal process group was described by participants as enhancing their competency as psychotherapists. Common themes included the experience of anxiety and a high level of emotion, and understanding how this experience might be similar for clients; increased self‐awareness; and increased competence in process issues. Many participants believed the process and content components of training were equally important to their development as psychotherapists.
