Reorienting attention and inhibition of return

In experiments examining inhibition of return (IOR), it is common practice to present a second cue at fixation during the cue-target interval. The purpose of this fixation cue is to reorient attention away from the cued location to ensure that the facilitative effects of spatial attention do not obscure IOR. However, despite their frequent use, relatively little is known about the relationship between fixation cues and IOR. In the present experiments, we examined the role of fixation cues by manipulating their presence in tasks that either did or did not require target identification. When the participants were required to either detect (Experiment 1A) or localize (Experiment 2A) a target, the magnitude of IOR was unaffected by the presence of a fixation cue. In contrast, when the participants were required to identify a target (Experiments 1B, 2B, and 3), IOR was observed only when a fixation cue was presented. This result was obtained regardless of the type of response that was required (two-alternative forced choice or go/no go). The effectiveness of the fixation cue in revealing IOR in these tasks is consistent with its putative role in reorienting attention away from the cued location.     

Effects of age on estimated familiarity in the process dissociation procedure: The role of noncriterial recollection

Research on recognition memory using the process dissociation procedure has suggested that although recollection (R) declines with age, familiarity (F) remains age invariant. However, this research has used relatively broad definitions of R. An important question concerns age-related changes in memory when R is defined in terms of specific event details. Yonelinas and Jacoby (1996a) required young participants to recollect specific, criterial details of a prior event and found evidence that recollection of noncriterial details elevated estimates of F yet still operated automatically. In the present study, the issue of noncriterial recollection was examined in the context of aging. The results replicated the effects of noncriterial recollection for the young, but not for the older adults, who also showed overall reduced levels of familiarity.     

A contextual change account of the directed forgetting effect

The authors propose that the costs and benefits of directed forgetting in the list method result from an internal context change that occurs between the presentations of 2 lists in response to a "forget" instruction. In Experiment 1 of this study, costs and benefits akin to those found in directed forgetting were obtained in the absence of a forget instruction by a direct manipulation of cognitive context change. Experiment 2 of this study replicated those findings using a different cognitive context manipulation and investigated the effects of context reinstatement at the time of recall. Context reinstatement reduced the memorial costs and benefits of context change in the condition where context had been manipulated and in the standard forget condition. The results are consistent with a context change account of directed forgetting.     

Expressed emotion and attributions in the carers of patients with Alzheimer's disease: the effect on carer burden

Burden of care, expressed emotion (EE), causal attributions, and salivary cortisol were assessed in 100 carers of patients with Alzheimer's disease. Forty-one carers were rated high EE, which was associated with higher scores of carer distress and strain, and greater reports of noncognitive features in the patient, but not with cortisol levels. High EE carers made more attributions personal to, and controllable by, the patient for negative events. Critical carers made more attributions of the patient's behavior that was idiosyncratic. Warmth toward the patient was associated with the opposite of this pattern. Overinvolved carers made attributions of the patient's behavior to causes external to the patient and internal to themselves. Cortisol levels were associated with self-reports of strain and distress.     

Effects of public posting,goal setting,and oral feedback on the skills of female soccer players

We evaluated the effects of public posting, goal setting, and oral feedback on the skills of 3 female high school soccer players during practice scrimmages. The dependent variables were the percentage of appropriate responses when the player (a) kept and maintained possession of the ball, (b) moved to an open position during a game restart (e.g., goal or corner kick), and (c) moved to an open position after passing the ball. We also assessed the extent to which changes in practice performances generalized to games. A social validity questionnaire was completed by both players and coaches to assess the acceptability of the intervention's goals, procedures, and outcomes. Results indicate that the intervention was effective in improving performances during practice scrimmages but produced limited generalization to game settings.     

A mean for all seasons

The averaging of scores differs from the averaging of numbers in that behavioral issues are built into scores. The behavioral issues are the weight attached to a score and the metric on which the scores have been gathered. A single equation is proposed, derived from Aczél’s (1966) model of the quasilinear mean, that encompasses the standard measures of central tendency. The equation allows for differential weighting of scores and also addresses the metric issue by incorporating response transformation.     

The Children's Attributional Style Interview: Developmental Tests of Cognitive Diathesis-Stress Theories of Depression

This paper presents an initial assessment of the Children's Attributional Style Interview (CASI), a newly designed measure for assessing attributional style in young children (age 5 and up). The CASI was used to conduct prospective tests of the reformulated helplessness (L. Y. Abramson, M. Seligman, & J. Teasdale, 1978) and the integrated hopelessness/self-esteem (G. I. Metalsky, T. E. Joiner, Jr., T. S. Hardin, & L. Y. Abramson, 1993) theories of depression in a sample of 147 5–10-year-old children. For comparison, the same tests were also conducted with the Children's Attributional Style Questionnaire-Revised (CASQ-R; N. J. Kaslow & S. Nolen-Hoeksema, 1991), a commonly used measure for assessing attributional style in older children (age 8 and up). The CASI evidenced support of the reformulated helplessness theory and partial support of the integrated hopelessness/self-esteem theory. The CASI also demonstrated good internal consistency. Thus, our findings provide initial support for the CASI as a methodologically sound measure of attributional style for children as young as 5 years old. Although preliminary, our findings also suggest possible developmental differences in how attributional style interacts with self-esteem and negative life stress. The CASI should prove to be a useful tool in furthering the understanding of the origins and development of attributional style in childhood, as well as its contribution to the understanding of the development and prevention of depressive symptomatology in children.     

At Both Ends of the Gun: Testing the Relationship Between Community Violence Exposure and Youth Violent Behavior

Much psychological inquiry has focused on understanding the contribution that exposure to urban violence makes to violent behavior among youth. However, other ways in which these variables may be related have been largely overlooked. This study compared four alternative social–ecological models of the link between community violence exposure and violent behavior to determine the degree to which (1) community violence exposure contributes to violent behavior, (2) violent behavior contributes to community violence exposure, (3) both are consequences of common antecedents, and (4) both are manifestations of the same higher order construct. Two hundred and seventy-seven adolescent offenders were interviewed about family, neighborhood, cognitive, and peer characteristics, in addition to violent behavior and community violence exposure. Results suggest that a plausible way to understand the association between community violence exposure and youth violent behavior is to consider both as representations of a general involvement in violence.     

Linguistic focus and memory: An eye movement study

We report an eyetracking study investigating the effects of linguistic focus on eye movements and memory during two readings of a text. Across two presentations of the text, a critical word either changed to a semantically related word or remained unchanged. Focus on the critical word was manipulated using context. Eye movements were monitored during reading, and there was a secondary task of detecting the word change. Results indicated that when a word changed, participants were more successful at detecting it when it was in focus. In the second display, there were more fixations and longer viewing times on a changed than on an unchanged word, but only when the critical word was in focus; eye movement data for changed and unchanged words did not differ when the word was not in focus. We suggest that linguistic focus leads to more detailed lexical semantic representations but not more effortful initial encoding of information.     

Prospective memory and pediatric traumatic brain injury: effects of cognitive demand.

This study investigated the effects of pediatric traumatic brain injury (TBI) on prospective memory. Fourteen children and 14 adolescents with TBI were compared with 25 and 23 noninjured children and adolescents, respectively. Based on a prefrontal model, the cognitive demand on the ongoing component of a prospective-memory task was manipulated. Overall, those with TBI had poorer prospective-memory performance than their noninjured peers. Performance was worse in a high cognitive-demand condition than a low, and younger children performed worse than adolescents. Decreases in performance from the low- to high-demand conditions were not significantly different between the two children's groups but were between the two adolescents' groups. Furthermore, the age and injury effects were reflected in the performances on executive function tests: the Self-ordered Pointing Task (SOPT), and the Stroop Color Word Interference Test. The Tower of London (TOL), which did not produce age or injury effects, was nevertheless found to be an important predictor of performance on the high-demand task in those with TBI. Although previous research has demonstrated impaired prospective memory performance in children with TBI, this study attempted to explain why this might occur, specifically that the prefrontal regions might be implicated.
