Does a behavioral and anatomical division exist between spatial and object working memory? In this article, we explore this question by testing human participants in simple visual working memory tasks. We compared a condition in which there was no location change with conditions in which absolute location change and absolute plus relative location change were manipulated. The results showed that object memory was influenced by memory for relative but not for absolute location information. Furthermore, we demonstrated that relative space can be specified by a salient surrounding box or by distractor objects with no touching surfaces. Verbal memory was not influenced by any type of spatial information. Taken together, these results indicate that memory for “where” influences memory for “what.” We propose that there is an asymmetry in memory according to which object memory always contains location information. 相似文献

The current study examined utilization of cognitive-behavioral therapy (CBT) by individuals receiving treatment for obsessive-compulsive disorder (OCD). Participants were 202 adults with primary DSM-IV OCD who enrolled in a longitudinal, observational study of the course of OCD and completed 2 years of annual follow-up interviews using the Longitudinal Interval Follow-Up Evaluation. One hundred twenty participants reported that a mental health professional recommended CBT for their OCD symptoms at some point during the 2-year follow-up period. One quarter (n = 31) of these participants did not initiate CBT despite receiving a treatment recommendation. Thirty-one percent of the 89 participants who entered CBT endorsed dropping out of CBT prematurely and less than one third received an adequate “dose” of CBT sessions. Self-reported CBT drop-out rates were significantly greater than attrition rates reported in clinical trials using intensive schedules of exposure and ritual prevention (EX/RP). Perceived environmental barriers and fears regarding treatment participation were the most frequently endorsed reasons for not participating or dropping out of CBT. Despite its efficacy for OCD, many individuals with clinically significant symptoms fail to initiate CBT when recommended by a mental health professional, receive treatments that are less intensive than those used in clinical trials, or drop out of treatment prematurely. Financial costs of CBT, difficulty attending sessions, and fears regarding treatment are significant barriers to initiating and completing therapy. 相似文献

Exposure to maternal vs. paternal partner violence,PTSD, and aggression in adolescent girls and boys
Marlene M. Moretti Ingrid Obsuth Candice L. Odgers Pratibha Reebye 《Aggressive behavior》2006,32(4):385-395
Adolescents who witness interparental violence (IPV) are at increased risk for perpetrating aggressive acts. They are also at risk for post‐traumatic stress disorder (PTSD). In this study, we examined the relation between exposure to maternal vs. paternal physical IPV and adolescent girls' and boys' aggressive behavior toward mothers, fathers, friends, and romantic partners. We also assessed the influence of PTSD (as assessed by the Diagnostic Interview for Children and Adolescents‐IV (DICA‐IV)) on the relation between exposure to IPV and aggressive behavior. Participants were 63 girls and 49 boys, ages 13–18, consecutively admitted to a youth correctional facility or assessment facility designated to serve aggressive and delinquent youth. Structural equation modeling was used to estimate unique relations between exposure to maternal vs. paternal IPV and youth aggression in relationships. Girls who observed their mothers' aggressive behavior toward partners were significantly more aggressive toward friends. Similarly, boys who witnessed their fathers' aggression were significantly more aggressive toward friends. Adolescent girls and boys who observed aggression by mothers toward partners reported significantly higher levels of aggression toward their romantic partners. Approximately one third of our sample met PTSD criteria; the relation between exposure to parental IPV and aggression was stronger for individuals who met criteria for PTSD. The implications of understanding the relations between parents' and their daughters' and sons' use of aggression are discussed within the context of providing support for families in breaking intergenerational patterns of violence and aggression.

The first law providing for the permanent, involuntary institutionalization of “feeble‐minded” individuals was passed in Illinois in 1915. This bill represented the first eugenic commitment law in the United States. Focusing on the consequences of this 1915 commitment law within the context of intelligence testing, eugenics, and the progressive movement, this paper will argue that the then newly devised Binet–Simon intelligence test facilitated the definition and classification of feeble‐mindedness that validated feeble‐mindedness theory, enabled the state to legitimize the eugenic diagnosis and institutionalization of feeble‐minded individuals, and especially empowered psychologists to carve out a niche for themselves in the courtroom as “experts” when testifying as to the feeble‐mindedness of individuals. 相似文献

Is the capacity of visual short-term memory (VSTM) limited by the number of objects or by the number of features? VSTM for objects with either one feature or two color features was tested. Results show that capacity was limited primarily by the number of colors to be memorized, not by the number of objects. This result held up with variations in color saturation, blocked or mixed conditions, duration of memory image, and absence or presence of verbal load. However, conjoining features into objects improved VSTM capacity when size-orientation and color-orientation conjunctions were tested. Nevertheless, the number of features still mattered. When feature heterogeneity was controlled, VSTM for conjoined objects was worse than VSTM for objects made of single features. Our results support a weak-object hypothesis of VSTM capacity that suggests that VSTM is limited by both the number of objects and the feature composition of those objects. 相似文献

Presenting a masked prime leading a target influences the perceived onset of the masking target (perceptual latency priming; Scharlau & Neumann, in press). This priming effect is explained by the asynchronous updating model (Neumann, 1982; Scharlau & Neumann, in press): The prime initiates attentional allocation toward its location, which renders a trailing target at the same place consciously available earlier. In three experiments, this perceptual latency priming by leading primes was examined jointly with the effects of trailing primes in order to compare the explanation of the asynchronous updating model with the onset-averaging and the P-center hypotheses. Experiment 1 showed that an attended, as well as an unattended, prime leads to perceptual latency priming. In addition, a large effect of trailing primes on the onset of a target was found. As Experiment 2 demonstrated, this effect is quite robust, although smaller than that of a leading prime. In Experiment 3, masked primes were used. Under these conditions, no influence of trailing primes could be found, whereas perceptual latency priming persisted. Thus, a nonattentional explanation for the effect of trailing primes seems likely. 相似文献

This study examined the self-esteem, perceived stigma, and disclosure practices of 48 adolescents who stutter divided into two age cohorts: younger (13, 14, and 15 years) and older (16, 17, and 18 years) adolescents. Results revealed that 41 (85%) of the participants scored within 1 S.D. from the mean on a standardized measure of self-esteem, indicative of positive self-esteem. Results also showed that stuttering did not present a stigmatizing condition for the majority (65%) of adolescents who stutter. However, 60% of participants indicated that they "rarely" or "never" discussed their stuttering. The younger adolescents perceived stuttering as a more negative and stigmatizing condition than older adolescents. Implications for understanding stuttering in adolescents are discussed. EDUCATIONAL OBJECTIVES: Readers will learn about and understand (a) the role of stigma, disclosure, and self-esteem in stuttering; (b) the methods used to evaluate stigma, disclosure, and self-esteem in adolescents; and (c) the similarities between adolescents who stutter and normative data on self-esteem and stigma scales. 相似文献
