Sex offenders, sentencing laws and pharmaceutical treatment: a prescription for failure

The phenomenon of adults who have sexual interests involving children as partners, or pedophiles, is considered among the most sociopathological of human conditions. Considerable literature is devoted to issues and problems associated with or related to pedophilia, including prevalence, etiology, treatment, and outcome studies. The sexual victimization of children, based upon data gathered from a number of sources, suggests an intractable problem that is national in scope. Recent manifestations of society's efforts to deal with the sexual victimization of children include the enactment of criminal sentencing laws that mandate the treatment of offenders with certain pharmaceutical agents, such as medroxy-progesterone acetate ("MPA"). Because sentencing laws as a rule vary widely from state to state, there is considerable variation as to who is subject to MPA treatment laws, and how such laws-including specific provisions, such as clinical criteria, if any, required for treatment; type and period of treatment plans; informed consent; etc-are implemented. Most important, these sentencing laws may have remarkably little relation to what is widely considered effective treatment for pedophilia disorders. We examine in detail the most recent sentencing laws pertaining to treatment of persons who have been convicted of sex offenses involving children as victims. Our critique may offer insight and suggestions as to how such sentencing laws can be more suitably tailored to the treatment needs of persons with pedophilia disorders.     

Training to Improve Calibration and Discrimination: The Effects of Performance and Environmental Feedback

This study investigated whether calibration and discrimination are distinct or related aspects of probability judgment accuracy by examining the effects of two different training techniques. Participants received either performance feedback or environmental feedback, and we measured their improvement in calibration and discrimination as a function of feedback type. Whereas performance feedback reduced participants' overconfidence and environmental feedback improved discrimination, neither type of feedback led to an improvement on the other component. In fact, environmental feedback led to an increase in overconfidence. We take these results as evidence that calibration and discrimination are dissociable abilities that require separate training techniques for improvement.     

Individuality and social influence in groups: inductive and deductive routes to group identity

A distinction between forms of social identity formation in small interactive groups is investigated. In groups in which a common identity is available or given, norms for individual behavior may be deduced from group properties (deductive identity). In groups in which interpersonal relations are central, a group identity may also be induced from individual group members' contributions, making individuality and individual distinctiveness a defining feature of the group (inductive identity). Two studies examined the prediction that depersonalization produced by anonymity has opposite effects for groups in which social identity has been induced or deduced. Results confirmed the prediction that depersonalization increases social influence in groups whose identity was more deductive. In contrast, depersonalization decreases social influence in inductive identity groups. Implications for the role of social identity in small groups are discussed.

Death anxiety and death depression in Spanish nurses

This study examined the dimensional structure of Tomás-Sábado and Gómez-Benito's Death Anxiety Inventory and Templer, et al.'s Death Depression Scale-Revised. The responses of 244 Spanish nurses to the Spanish forms of both scales were evaluated by means of a principal axis factor analysis with direct Oblimin rotation. Five significant factors were identified: Internally Generated Death Anxiety, Death Depression, Externally Generated Death Anxiety, Death Threat, and Death Sadness, accounting for 51.6% of the variance. The distribution of the factor loadings for the items of both scales on the five factors supported the discriminant validity of the constructs specific to each of the scales and justified their use in evaluating death anxiety and death depression independently.     

Strength of visual percept generated by famous faces perceived without awareness: effects of affective valence, response latency, and visual field

Participants who were unable to detect familiarity from masked 17 ms faces (Stone and Valentine, 2004 and Stone and Valentine, in press-b) did report a vague, partial visual percept. Two experiments investigated the relative strength of the visual percept generated by famous and unfamiliar faces, using masked 17 ms exposure. Each trial presented simultaneously a famous and an unfamiliar face, one face in LVF and the other in RVF. In one task, participants responded according to which of the faces generated the stronger visual percept, and in the other task, they attempted an explicit familiarity decision. The relative strength of the visual percept of the famous face compared to the unfamiliar face was moderated by response latency and participants' attitude towards the famous person. There was also an interaction of visual field with response latency, suggesting that the right hemisphere can generate a visual percept differentiating famous from unfamiliar faces more rapidly than the left hemisphere. Participants were at chance in the explicit familiarity decision, confirming the absence of awareness of facial familiarity.     

Further evidence for the role of inferential reasoning in forward blocking

Previous studies on human causal learning (De Houwer & Beckers, 2003; De Houwer, Beckers, & Glautier, 2002) showed that secondary task difficulty (performing an easy vs. a difficult secondary task during the main causal learning task) and ceiling information (outcome occurs with a maximal vs. submaximal intensity) had an influence on forward blocking (i.e., lower causal ratings for cue T when AT+ trials are preceded by A+ trials than when no A+ trials are presented). We extended these studies by also examining self-reports of participants about the reasons behind their causal ratings. Blocking was found only for participants who reported an appropriate blocking inference. Furthermore, secondary task difficulty and ceiling information influenced the number of participants who reported an appropriate blocking inference. These findings point to a major impact of inferential reasoning in human causal learning.     

The cognitive neuroscience of auditory distraction

We are often aware of the content of distracting sound, although typically remain unaware of the processes by which that sound is disruptive. Disruption can occur even when the sound is ignored and unrelated to the task being performed. In a recent major development, Gisselg?rd et al. have used positron emission tomography to reveal how distracting sounds recruit the involvement of dorsolateral prefrontal cortex.     

Mapping brain maturation and cognitive development during adolescence

Non-invasive mapping of brain structure and function with magnetic resonance imaging (MRI) has opened up unprecedented opportunities for studying the neural substrates underlying cognitive development. There is an emerging consensus of a continuous increase throughout adolescence in the volume of white matter, both global and local. There is less agreement on the meaning of asynchronous age-related decreases in the volume of grey matter in different cortical regions; these might equally represent loss ("pruning") or gain (intra-cortical myelination) of tissue. Functional MRI studies have so far focused mostly on executive functions, such as working memory and behavioural inhibition, with very few addressing questions regarding the maturation of social cognition. Future directions for research in this area are discussed in the context of processing biological motion and matching perceptions and actions.     

Can we really do without self-esteem? Comment on Crocker and Park (2004)

Because self-esteem plays a central role in managing anxiety and provides a superordinate goal that organizes much human behavior, the authors conclude that it would be extremely difficult and probably impossible for people to stop pursuing self-esteem. Although they agree that investment in others' welfare may circumvent some of the negative consequences of self-esteem pursuit, the authors argue that the self-esteem implications of other-oriented behavior will inevitably be a powerful motivating force. Finally, the authors propose that self-esteem derived from self-determined standards of value may reduce defensiveness, closed-mindedness, and indifference to others, as well as promote personal growth, but they acknowledge the daunting barriers to the attainment of such self-determined bases of self-worth.
