The Psychological Record - The present experiment examined temporal discounting across 3 different age bands: adolescents, adults, and older adults (mean ages 14, 46, and 73 years, respectively). A...     

Cognitive-behavioural therapy for young children with anxiety disorders: Comparison of a Child + Parent condition versus a Parent Only condition

The present study compared the efficacy of a group-based cognitive-behavioural treatment (GCBT) delivered exclusively to parents of young anxious children (between 4 and 8 years of age) with the same intervention delivered to both children and parents, relative to a Wait-list Control condition. Parents of children in the Parent Only condition (N = 25) received 10 weekly sessions of GCBT whereas children and parents in the Parent + Child condition (N = 24) each received 10 weekly sessions of GCBT. Intent-to-treat analyses indicated that both active treatment conditions were superior to the Wait-list condition (N = 11), with 55.3% of children in the Parent Only condition and 54.8% of children in the Parent + Child condition no longer meeting criteria for their principal diagnosis at post-treatment. These treatment gains were maintained in both treatment conditions at six-month and 12-month follow-up assessments. There were no significant differences between the two active conditions on other outcome measures including parental psychopathology and parenting style. However, an unexpected finding was that parenting satisfaction and to some extent parenting competence reduced significantly from pre- to post-treatment regardless of the active treatment condition. The present results suggest that GCBT delivered exclusively to parents of young anxious children may be a viable treatment alternative for improving accessibility to efficacious treatments for children with anxiety disorders and for reducing costs associated with mental health care delivery.     

Effects of subcultural differences on country and product evaluations

Most cross‐cultural studies on country of origin or product‐country image (PCI) effects have implicitly assumed that national markets are composed of homogeneous consumers. Although many investigations in this field are described as cross‐cultural, most are in fact cross‐national. The overarching hypothesis of the present research is that PCI effects may vary across subcultures within a country. The results indicate that subcultural differences exist in the evaluation of culturally affiliated countries and their products. Cognitive responses converged to show that consumers' perceived linkages significantly influence the weight given to the country of origin in product evaluations. Several implications for managers and academic researchers are discussed. Copyright © 2003 Henry Stewart Publications.     

Including Manual Signing as Nontargeted Information When Using a Constant Time Delay Procedure to Teach Receptive Identification of Packaged Food Items

This investigation extends the constant time delay research base by embedding nontargeted information in the task direction when teaching communication skills. Specifically, instructors taught receptive identification of packaged food items to 4 secondary students with moderate to severe disabilities and evaluated generalization to the community. In addition, instructors included the manual sign for each food item. The instructional strategy was a constant time delay procedure using a 5-s delay interval. The intervention, conducted within a multiple probe design across behaviors replicated across students, resulted in the acquisition and generalization of receptive identification of packaged food items by 3 out of 4 of the students. In addition, the students acquired the nontargeted manual signs with an average of 60% percent in the final probe session.     

Telemetry provides new insights into entrainment of activity wheel circadian rhythms and the role of body temperature in the development of ulcers in the activity-stress paradigm

Two methods of monitoring the circadian rhythm of activity in rodents: (1) an activity wheel cage, which detects the number of wheel revolutions, and (2) an internal radio transmitter, which records gross motor activity (GMA) of the animal, were compared in both normal circadian cycles and during the development of activity-stress ulcers. Rats were implanted with a biotelemetry transmitter that detected GMA and body temperature (BT) and placed in activity wheel cages. A 12 hour/12 hour light/dark cycle was maintained throughout the experiment. Subjects were subdivided into two groups: (1) unlimited access to activity wheel (AW) cages and (2) locked activity wheel (LW) cages. Following an ad-libitum habituation period, animals were allowed food access for 1 hour/day during the light. In the habituation period, the animals showed higher GMA and BT during the dark phase when housed in AW cages than in LW cages. Both GMA and number of wheel revolutions increased dramatically after the onset of food restriction for the AW animals. There was a deleterious drop in BT in AW animals as the food-restricted period continued and a significant correlation existed between severity of ulcerations and BT. The findings of this experiment demonstrate that the activity wheel imposes an alternation of the circadian cycle, which, in turn, influences rhythmicity through reentrainment. Additionally, in the activity-stress paradigm, a significant drop in BT correlates with severity of ulcerations. A disrupted circadian cycle, involving hypothermia, is proposed as the mechanism underlying the demise of animals in the activity-stress paradigm.     

Abiding by Sri Lanka Qadri Ismail's way

Qadri Ismail's book, Abiding by Sri Lanka: On Peace, Place, and Postcoloniality (2005) suggests that literary theory might help Sri Lankans re-imagine the colonial social categories and histories that underwrite their long-running conflict. Ismail also argues that the social sciences (particularly anthropology) and history fail Sri Lanka. They fail either because, like anthropology, their colonial origins render them epistemologically unable to ‘abide by’ Sri Lanka (or to see its politics as political); or because, like history, their embrace of an empiricist belief in an objectively real history betrays them into reconfirming nationalism. My article will argue that while the first part of Ismail's thesis is fascinating and useful (if a bit lacking in practical details), his claim that anthropology and history writing as such must be ‘de-authorized’ is too broad. It concludes by arguing for a cease-fire in Sri Lanka.     

Cross-sectional and prospective associations between cognitive appraisals and posttraumatic stress disorder symptoms following stroke

This study examined cross-sectional and prospective associations between cognitive appraisals and posttraumatic stress disorder (PTSD) symptoms following stroke. While in hospital, stroke patients (n=81) completed questionnaires assessing cognitive appraisals (i.e., negative cognitions about the self, negative cognitions about the world, and self-blame) and PTSD symptoms. PTSD symptoms were assessed again 3 months later when all patients had been discharged from hospital (n=70). Significant correlations were found between the time 1 measures of negative cognitions about the self and the world, but not self-blame, and the severity of PTSD symptoms measured at time 1 and at time 2. Regression analyses revealed that cognitive appraisals explained a significant amount of variance in the severity of PTSD symptoms at time 1, with negative cognitions about the self-emerging as a significant predictor. In contrast, time 1 cognitive appraisals were unable to explain additional variance in time 2 PTSD severity over and above that explained by time 1 PTSD severity. The findings therefore provide only weak support for Ehlers and Clark's cognitive model of PTSD.     

Temperament and externalizing behavior: social preference and perceived acceptance as protective factors

The purpose of this study was to explore the role of social preference and perceived acceptance as moderators of the relation between child temperament and externalizing behavior. Participants included 399 children evaluated at pre-kindergarten and kindergarten assessments. Pre-kindergarten children characterized by high temperamental Surgency/Extraversion were more likely to exhibit hyperactivity and aggression in the kindergarten classroom. In addition, kindergarten perceived acceptance and social preference moderated the relation between pre-kindergarten Surgency/Extraversion and kindergarten hyperactivity for girls only. Girls who were characterized by high temperamental Surgency/Extraversion, high perceived acceptance, and low social preference were at risk for higher levels of teacher-reported and peer-nominated hyperactivity. In contrast, accurately high perceived acceptance was a protective factor for high temperamental Surgency/Extraversion. Findings are discussed in terms of risk and protective factors for externalizing behavior.     

Facial expressions modulate the gaze orienting effect on sound localization judgement

Recent studies have shown that cueing eye gaze can affect the processing of visual information, and this phenomenon is called the gaze-orienting effect (visual-GOE). Emerging evidence has shown that the cueing eye gaze also affects the processing of auditory information (auditory-GOE). However, it is unclear whether the auditory-GOE is modulated by emotion. We conducted three behavioural experiments to investigate whether cueing eye gaze influenced the orientation judgement to a sound, and whether the effect was modulated by facial expressions. The current study set four facial expressions (angry, fearful, happy, and neutral), manipulated the display type of facial expressions, and changed the sequence of gaze and emotional expressions. Participants were required to judge the sound orientation after facial expressions and gaze cues. The results showed that the orientation judgement of sound was influenced by gaze direction in all three experiments, and the orientation judgement of sound was faster when the face was oriented to the target location (congruent trials) than when the face was oriented away from the target location (incongruent trials). The modulation of emotion on auditory-GOE was observed only when gaze shifted followed by facial expression (Exp3); the auditory-GOE was significantly greater for angry faces than for neutral faces. These findings indicate that auditory-GOE as a social phenomenon exists widely, and the effect was modulated by facial expression. Gaze shift before the presentation of emotion was the key influencing factor for the emotional modulation in an auditory target gaze-orienting task. Our findings suggest that the integration of facial expressions and eye gaze was context-dependent.
