The effects of divided attention at study and test on false recognition: A comparison of DRM and categorized lists 总被引:1,自引:0,他引:1
Three experiments investigated the effects of divided attention at encoding and retrieval on false recognition. In Experiment 1, participants studied word lists in either full or divided attention (random number generation) conditions and then took part in a recognition test with full attention. In Experiment 2, after studying word lists with full attention, participants carried out a recognition test with either full or divided attention. Experiment 3 manipulated attention at both study and test. We also compared Deese/Roediger-McDermott (DRM) and categorized lists, due to recent claims regarding the locus of false memories produced by such lists (Smith, Gerkens, Pierce, & Choi, 2002). With both list types, false "remember" responses were reduced by divided attention at encoding and increased by divided attention at retrieval. The findings suggest that the production of false memories occurs as a result of the generation of associates at encoding and failures of source monitoring retrieval. Crucially, this is true for both DRM and categorized lists. 相似文献

Rodent ultrasonic vocalizations (USVs) are ethologically critical social signals. Rats emit 22 kHz USVs and 50 kHz USVs, respectively, in conjunction with negative and positive affective states. Little is known about what controls emotional reactivity to these social signals. Using male Sprague–Dawley rats, we examined unconditional and conditional freezing behavior in response to the following auditory stimuli: three 22 kHz USVs, a discontinuous tone whose frequency and on–off pattern matched one of the USVs, a continuous tone with the same or lower frequencies, a 4 kHz discontinuous tone with an on–off pattern matched to one of the USVs, and a 50 kHz USV. There were no differences among these stimuli in terms of the unconditional elicitation of freezing behavior. Thus, the stimuli were equally neutral before conditioning. During differential fear conditioning, one of these stimuli (the CS+) always co-terminated with a footshock unconditional stimulus (US) and another stimulus (the CS−) was explicitly unpaired with the US. There were no significant differences among these cues in CS+-elicited freezing behavior. Thus, the stimuli were equally salient or effective as cues in supporting fear conditioning. When the CS+ was a 22 kHz USV or a similar stimulus, rats discriminated based on the principal frequency and/or the temporal pattern of the stimulus. However, when these same stimuli served as the CS−, discrimination failed due to generalization from the CS+. Thus, the stimuli differed markedly in the specificity of conditioning. This strikingly asymmetrical stimulus generalization is a novel bias in discrimination. 相似文献

The purpose of the current study was to operationalize the phenomenon of body deception, describe its theoretical importance, and validate its existence in an experimental paradigm. The definition of body deception includes the intentional misrepresentation of information about appearance to others. The present study examined body deception in a controlled experimental study of male and female same-sex peer groups using a series of hierarchical linear models. Ninety male and 90 female undergraduates were randomized to an experimental same-sex peer group or individual control condition. The results suggested that both men and women used body deception among peers, but men's body deception was muscularity driven whereas women's was thinness driven. Body dissatisfaction was significantly predictive of the degree of body deception used by both genders and it was significantly related to peer group membership. An integrated model for the role of body deception in body image disturbance is proposed. 相似文献

Behaviorally inhibited children display a temperamental profile characterized by social withdrawal and anxious behaviors.
Previous research, focused largely on adolescents, suggests that attention biases to threat may sustain high levels of behavioral
inhibition (BI) over time, helping link early temperament to social outcomes. However, no prior studies examine the association
between attention bias and BI before adolescence. The current study examined the interrelations among BI, attention biases
to threat, and social withdrawal already manifest in early childhood. Children (N = 187, 83 Male, M
age
= 61.96 months) were characterized for BI in toddlerhood (24 & 36 months). At 5 years, they completed an attention bias task
and concurrent social withdrawal was measured. As expected, BI in toddlerhood predicted high levels of social withdrawal in
early childhood. However, this relation was moderated by attention bias. The BI-withdrawal association was only evident for
children who displayed an attention bias toward threat. The data provide further support for models associating attention
with socioemotional development and the later emergence of clinical anxiety. 相似文献

Research provides strong support for the efficacy and effectiveness of cognitive behavioral therapy (CBT) for the treatment
of childhood internalizing disorders. Given evidence for limited dissemination and implementation of CBT outside of academic
settings, efforts are underway to improve its transportability so that more children with mental health needs may benefit
from treatment. Creative modifications to existing treatments aim to deliver CBT for anxiety disorders and depression in a
more transportable format. Notable progress has been made within the areas of computerized CBT, camp-based CBT, school-based
CBT, and CBT delivered through primary care settings. These approaches are discussed within the context of key elements of
transportability that are particularly germane to the dissemination and implementation of child treatments. 相似文献

Trichotillomania (TTM), a repetitive hair-pulling disorder, is underrepresented in the clinical literature. The current project explores the relationship between affective regulation and disordered hair-pulling. Previous research suggests that cycles of emotional states are correlated with the disorder and may induce, reinforce, or otherwise contribute to hair-pulling behavior. We use anonymous internet survey responses from 1162 self-identified hair-pullers to address four questions about affective regulation in people with TTM: (1) Do hair-pullers experience greater difficulty “snapping out” of affective states than non-pullers? (2) Does difficulty with emotional control correlate with TTM severity? (3) Are subtypes identifiable based on the emotions that trigger hair-pulling behavior? (4) Does difficulty “snapping out” of an emotion predict whether that emotion triggers pulling behavior? The results showed a small-to-moderate relationship between affective regulation and problematic hair-pulling. In addition, individual patterns of emotion regulation were systematically related to emotional cues for hair-pulling as well as overall hair-pulling severity. These findings contribute to an understanding of the phenomenology of TTM and provide empirical support for treatments focused on affect regulation. 相似文献

With the sustainable consumption paradigms, corporate social responsibilities (CSR) across industries have been under scrutiny. However, little research exists on how brand's business model and consumers' characteristics are intertwined to influence CSR evaluation. Our study aims to examine how the brand type (e.g., fast vs. slow business model) influences the relationships among CSR-brand fit, authenticity, and skepticism, thus improving attitudes toward the brand. In addition, based on the implicit theory, how the consumer's incremental mindset (vs. entity) influences a brand's CSR evaluations are studied. Through two studies, our findings demonstrate consumers perceived a higher CSR-brand fit for the slow fashion/food brand than the fast fashion/food brand. A higher CSR-brand fit heightened the CSR authenticity and alleviated skepticism, which in turn resulted in positive brand evaluations. Importantly, incremental mindsets weakened the effect of brand type on CSR-brand fit. As one of the first studies to examine the relationship between consumers' implicit theory orientation and a brand's CSR message, our findings demonstrate that an incremental mindset is a powerful consumer characteristic in evaluating a brand's CSR activities that are less congruent with the brand's established business model. 相似文献

Two experiments were conducted to evaluate the ability of younger and older adults to recognize 3-D object shape from patterns of optical motion. In Experiment 1, participants were required to identify dotted surfaces that rotated in depth (i.e., surface structure portrayed using the kinetic depth effect). The task difficulty was manipulated by limiting the surface point lifetimes within the stimulus apparent motion sequences. In Experiment 2, the participants identified solid, naturally shaped objects (replicas of bell peppers, Capsicum annuum) that were defined by occlusion boundary contours, patterns of specular highlights, or combined optical patterns containing both boundary contours and specular highlights. Significant and adverse effects of increased age were found in both experiments. Despite the fact that previous research has found that increases in age do not reduce solid shape discrimination, our current results indicated that the same conclusion does not hold for shape identification. We demonstrated that aging results in a reduction in the ability to visually recognize 3-D shape independent of how the 3-D structure is defined (motions of isolated points, deformations of smooth optical fields containing specular highlights, etc.). 相似文献

The Department of Veterans Affairs (VA) requires that all VA hospitals and clinics provide access to evidence-based psychotherapies (EBPs). Despite these widespread dissemination efforts, only a minority of Veterans receive EBP services. Reasons for these low rates of EBP utilization are largely unknown. This study examined the characteristics of Veterans with posttraumatic stress disorder (PTSD) who did (Initiation group) and did not (No-Initiation group) initiate a VA-approved EBP after participating in an information session. Veterans chose their preferred treatment from a menu of EBPs. Results demonstrated that Veterans in the No-Initiation group had longer periods of time between their referral and first EBP visit. Among Veterans in the Initiation group, the majority (68%) initiated a trauma-focused EBP as their first or second treatment, suggesting that providing a range of treatment options did not negatively impact their willingness to engage in PTSD treatment. Results are discussed in terms of VA initiatives to improve access to and initiation of mental health care for Veterans. 相似文献
