Contour grouping inside and outside of facial contexts

We examine how contours group in isolation compared with when they are embedded in face-like contexts. As previously shown, contours that seem to group by phenomenological observation also show powerful effects on task performance: with contours that group, selective attention to one while ignoring another is poor (as indexed by Garner Interference (GI), but not Stroop Interference), whereas divided attention across contours is good. With contours that do not group, however, the reverse happens. Here we test pairs of curved lines (parentheses) displayed either in isolation or within contexts including cartoon faces, where these curves may serve as mouths or eyebrows. The results with isolated contours replicate previous findings of poor selective attention, but within face-like contexts the same contours showed nearly perfect selective attention (i.e., zero GI). Thus, contour grouping was weaker inside than outside of faces, a finding that contrasts with the widely-held belief that faces are processed configurally, not by local features.     

The Koala Fear Questionnaire: a standardized self-report scale for assessing fears and fearfulness in pre-school and primary school children

The Koala Fear Questionnaire (KFQ) is a standardized self-report scale for assessing fears and fearfulness in children aged between 4 and 12 years. The current article presents six studies which examined the reliability and validity of the KFQ. Study 1 (N=108) demonstrated that the visual fear scales of Koala bears as employed in the KFQ are highly comparable to the standard 3-point scales that are used in other childhood fear measures. Study 2 (N=163) provided support for the convergent validity of the KFQ in a sample of 8- to 14-year-old children. That is, the scale correlated substantially with alternative measures of childhood fear and anxiety. Study 3 (N=189) showed that the KFQ possesses good internal consistency and test-retest stability in a group of 8- to 11-year-old children. The results of Studies 4 (N=129) and 5 (N=176) indicated that the KFQ is suitable for children aged 4 to 6 years and demonstrated that the psychometric properties of the scale in younger children are highly similar to those obtained in older children. Study 6 (N=926) showed that the factor structure of the KFQ was theoretically meaningful: although the data clearly pointed in the direction of one factor of general fearfulness, spurs of the commonly found five-factor solution of childhood fear were found in the KFQ. Altogether, the KFQ seems to be a valuable addition to the instrumentarium of clinicians and researchers who are working with fearful and anxious children.     

Trajectories leading to school-age conduct problems

The present study applied a semiparametric mixture model to a sample of 284 low-income boys to model developmental trajectories of overt conduct problems from ages 2 to 8. As in research on older children, 4 developmental trajectories were identified: a persistent problem trajectory, a high-level desister trajectory, a moderate-level desister trajectory, and a persistent low trajectory. Follow-up analyses indicated that initially high and low groups were differentiated in early childhood by high child fearlessness and elevated maternal depressive symptomatology. Persistent problem and high desister trajectories were differentiated by high child fearlessness and maternal rejecting parenting. The implications of the results for early intervention research are discussed, with an emphasis on the identification of at-risk parent-child dyads.     

Preference for human direct gaze in infant chimpanzees (Pan troglodytes)

We studied gaze perception in three infant chimpanzees (Pan troglodytes), aged 10-32 weeks, using a two-choice preferential-looking paradigm. The infants were presented with two photographs of a human face: (a) with the eyes open or closed, and (b) with a direct or an averted gaze. We found that the chimpanzees preferred looking at the direct-gaze face. However, in the context of scrambled faces, the infants showed no difference in gaze discrimination between direct and averted gazes. These findings suggest that gaze perception by chimpanzees may be influenced by the surrounding facial context. The relationship between gaze perception, face processing, and the adaptive significance of gaze perception are discussed from an evolutionary perspective.     

Learning about life and death in early childhood

have argued that young children initially understand biological phenomena in terms of vitalism, a mode of construal in which "life" or "life-force" is the central causal-explanatory concept. This study investigated the development of vitalistic reasoning in young children's concepts of life, the human body and death. Sixty preschool children between the ages of 3 years, 7 months and 5 years, 11 months participated. All children were initially given structured interviews to assess their knowledge of (1) human body function and (2) death. From this sample 40 children in the Training group were taught about the human body and how it functions to maintain life. The Control group (n=20) received no training. All 60 children were subsequently reassessed on their knowledge of human body function and death. Results from the initial interviews indicated that young children who spontaneously appealed to vitalistic concepts in reasoning about human body functioning were also more sophisticated in their understanding of death. Results from the posttraining interviews showed that children readily learned to adopt a vitalistic approach to human body functioning, and that this learning coincided with significant development in their understanding of human body function, and of death. The overall pattern of results supports the claim that the acquisition of a vitalistic causal-explanatory framework serves to structure children's concepts and facilitates learning in the domain of biology.     

The future of the American Group Psychotherapy Association: whither we goest?

The author describes his perspective about what the future holds for the American Group Psychotherapy Association (AGPA). Utilizing Nitsun's (1996) construct of the "anti-group" as an organizing metaphor, he delineates the destructive forces both within and outside the organization that are currently affecting it, and then describes how they can be transformed into instruments for positive development. He suggests that the AGPA can and must continue to provide a "holding environment" (Winnicott, 1960) for professionals interested in working with people in groups. In addition, he asserts that the organization will build upon its remarkable response to the September 11, 2001 debacle in the United States to expand its services to those who have been traumatized. Beyond this, he underscores the importance of the AGPA consolidating and expanding its various educational offerings into a coherent package that will meet the needs of any and all who are interested in learning about how to work effectively with groups. In these and other ways, he contends that the AGPA will thereby confirm Nitsun's assertion that anti-group forces can be transformed, and that organizations that confront these forces constructively can not only survive but thrive.     

An experiential approach to the inpatient anger management group

Groups that target aggression on the inpatient milieu usually use psycho-educational and cognitive-behavioral techniques. In contrast, this article presents an experiential approach that targets the moment-by-moment experience within the inpatient group. It makes unique use of group-closing relaxation exercises that facilitate cohesion, consolidate the affectively charged material generated during the session, and reorganize patients' emotional/cognitive understanding of themselves and the world around them. These groups also give patients the opportunity to negotiate the affective residue associated with past aggressive acts, and the opportunity to examine the personal meaning and underlying assumptions behind ongoing group interactions. We describe several techniques or modes of intervention. The authors also use case examples to illustrate the theory, technique, and impact the approach can have on its members.     

The construct validity of depressive personality disorder

This study examined the construct validity of depressive personality disorder (DPD: American Psychiatric Association, 1994). Adult psychiatric outpatients (N = 900) underwent comprehensive Axis I and II evaluations and provided data on 4,768 of their 1st-degree relatives. Despite modest overlap, DPD was not redundant with any Axis I or II disorder. Participants with DPD exhibited more Axis I and Axis II comorbidity, and greater psychosocial dysfunction, than participants without DPD. Relatives of participants with DPD had higher rates of mood disorders, alcohol abuse, and antisocial personality. Results are consistent with findings of several other similar investigations. The authors argue that DPD is a valid construct and should be conceptualized as a personality disorder as opposed to a mood disorder.     

Effects of daily events on mood states in major depressive disorder

Major depressive disorder (MDD) is characterized by high negative affect (NA) and low positive affect (PA), but little is known about emotional reactivity in daily life. The authors used experience sampling methodology to investigate changes in NA and PA following minor daily events in MDD compared with healthy participants. Contrary to expectation, MDD participants did not report more frequent negative events, although they did report fewer positive events. Multilevel regression showed that both NA and PA responses to negative events were blunted in the MDD group, whereas responses to positive events were enhanced. NA responses to negative events persisted longer in MDD participants. Depressed participants with a positive family history or longer current episodes showed relatively greater NA responses to negative events.
