Neuropsychological Characteristics of Adolescents With Conduct Disorder: Association With Attention-Deficit–Hyperactivity and Aggression

The purpose of this study was to determine whether an association exists between neuropsychological deficits and conduct disorder (CD) with and without concurrent attention-deficit–hyperactivity disorder (ADHD). In addition, we explored the differential neuropsychological performance of aggressive and nonaggressive CD adolescents and the combined effect of this behavioral status and ADHD on performance. Fifty-nine adolescents (mean age of 15.4 years) who met the criteria for CD were compared with 29 controls comparable in age, gender, and socioeconomic status. A neuropsychological battery of current tests measuring executive functions and a battery of language tests were used in the study. Multivariate analyses showed that, compared with controls, CD adolescents had significantly lower verbal skills but did not differ on executive function measures. However, the lower verbal performance of CD adolescents is not explained by the existence of a CD subgroup with concomitant ADHD or aggressiveness. The study confirms with a sample of CD adolescents the association between verbal deficits and antisocial behavior when socioeconomic status is controlled. Our results also demonstrate that CD per se can be a sufficient condition for such deficits.     

The experience of ‘healing stories’ in the life narrative: A grounded theory

‘healing stories' are part of an emergent narrative literature in psychology and counselling. This research explored the subjective experience of ‘healing stories’ within the context of individual's life narratives. A grounded theory (Strauss and Corbin, 1990) method of analysis was used to generate and analyse six participant's life narratives. Analysis of these accounts revealed three categories. The first is the context of struggle that preceded the healing process. participants told of struggle in their relationships with others as well as turmoil in their experience of themselves. The second category, the healing process reflected the participants' growing awareness of life's existential givens (Yalom, 1980). This represented a personal exploration that opened lparticipants to a ‘healing story’ that offered them an insight into choices and possibilities for liberation. The third category illustrated that in the ongoing struggle the ‘healing story’ has continued to provide inspiration in the participants' lived experience as an ‘evoked companion’ (Stern, 1985). This research posited a core dynamic whereby participants' experience of their ‘healing story’ provided not only an initial inspiration that was healing but also, in their ongoing struggle, the ‘healing story’ continued to inspire their lived experience.     

Reinventing the University Through the Teaching of Diversity

University reform encompasses an increased emphasis on the social and emotional development of students. In particular, the development of caring, empathy, and community are emphasized. This team of psychology professors approaches the task of university reform by presenting both its philosophy of diversity inclusion and specific inclusion strategies as means of promoting enhanced development of our students. Although the discipline of psychology is used as an example, the philosophical argument and the strategic approaches may be applied to other disciplines.     

Age differences in accuracy and choosing in eyewitness identification and face recognition

Studies of aging and face recognition show age-related increases in false recognitions of new faces. To explore implications of this false alarm effect, we had young and senior adults perform (1) three eye-witness identification tasks, using both target present and target absent lineups, and (2) and old/new recognition task in which a study list of faces was followed by a test including old and new faces, along with conjunctions of old faces. Compared with the young, seniors had lower accuracy and higher choosing rates on the lineups, and they also falsely recognized more new faces on the recognition test. However, after screening for perceptual processing deficits, there was no age difference in false recognition of conjunctions, or in discriminating old faces from conjunctions. We conclude that the false alarm effect generalizes to lineup identification, but does not extend to conjunction faces. The findings are consistent with age-related deficits in recollection of context and relative age invariance in perceptual integrative processes underlying the experience of familiarity.     

Mathematical engineering and mathematical change 1

In this paper, I introduce and examine the notion of “mathematical engineering” and its impact on mathematical change. Mathematical engineering is an important part of contemporary mathematics and it roughly consists of the “construction” and development of various machines, probes and instruments used in numerous mathematical fields. As an example of such constructions, I briefly present the basic steps and properties of homology theory. I then try to show that this aspect of contemporary mathematics has important consequences on our conception of mathematical knowledge, in particular mathematical growth.     

PAST: Viewing the programming process

A software package called PAST (Programmer Assessment Software Tools) is described. PAST was designed as a research and diagnostic tool to analyze how programmers develop and test program code. PAST uses line changes between successive compiles to estimate a programmer’s cognitive processing. Line changes are highlighted and graphically presented between any two versions or compiles. Summary graphs and statistics across all versions also are provided. Applications of PAST for expanding our understanding of programming and applying it to research, teaching, and learning are discussed.     

School Counselors and Gifted Kids: Respecting Both Cognitive and Affective

Giftedness can be both an asset and a burden when gifted students respond to developmental challenges. Characteristics associated with high intellectual ability likely affect how gifted students experience social, emotional, and career development, regardless of level of academic achievement. Counselors' lack of awareness of such qualitative differences, as well as positive and negative biases, may interfere with the therapeutic relationship. Characteristics related to giftedness, vulnerabilities, concerns, and counseling strategies are the focus of this article.     

Differentiating emotional processing and attention in psychopathy with functional neuroimaging

Individuals with psychopathy are often characterized by emotional processing deficits, and recent research has examined the specific contexts and cognitive mechanisms that underlie these abnormalities. Some evidence suggests that abnormal features of attention are fundamental to emotional deficits in persons with psychopathy, but few studies have demonstrated the neural underpinnings responsible for such effects. Here, we use functional neuroimaging to examine attention–emotion interactions among incarcerated individuals (n = 120) evaluated for psychopathic traits using the Hare Psychopathy Checklist–Revised (PCL-R). Using a task designed to manipulate attention to emotional features of visual stimuli, we demonstrate effects representing implicit emotional processing, explicit emotional processing, attention-facilitated emotional processing, and vigilance for emotional content. Results confirm the importance of considering mechanisms of attention when evaluating emotional processing differences related to psychopathic traits. The affective-interpersonal features of psychopathy (PCL-R Factor 1) were associated with relatively lower emotion-dependent augmentation of activity in visual processing areas during implicit emotional processing, while antisocial-lifestyle features (PCL-R Factor 2) were associated with elevated activity in the amygdala and related salience network regions. During explicit emotional processing, psychopathic traits were associated with upregulation in the medial prefrontal cortex, insula, and superior frontal regions. Isolating the impact of explicit attention to emotional content, only Factor 1 was related to upregulation of activity in the visual processing stream, which was accompanied by increased activity in the angular gyrus. These effects highlight some important mechanisms underlying abnormal features of attention and emotional processing that accompany psychopathic traits.     

Modulation of the Irrelevant Sound Effect by Organizational Factors: Further Evidence from Streaming by Location

An irrelevant sequence of discrete auditory tokens disrupts serial recall markedly if successive tokens differ, but the disruption is less marked if the sound is repeated. However, the relation of stimulus mismatch and degree of disruption with serial recall seems to be modulated by organizational principles such as streaming by pitch and streaming by location. The current empirical work replicates the finding that the impact of changing sequences can be reduced if tokens are assigned to different locations in such a way as to form separate streams, each containing sequences of repeated tokens. This study shows that this phenomenon is not a consequence of reducing the number of tokens per stream.
