Switching between goals mediates the attentional blink effect 总被引:1,自引:0,他引:1
Humans are fundamentally limited in processing information from the outside world. This is particularly evident in the attentional blink (AB), the impaired ability to identify the second of two targets presented in close succession. We report findings from three experiments showing that the AB is significantly reduced when observers are set to achieve one single goal (reporting combinations of the two targets) instead of separate goals (reporting the two targets). This finding raises questions about the nature of AB, and suggests that processes involved in goal-switching must be taken into account by theories of the AB phenomenon. 相似文献

The present experiment investigated reinstatement of fear in humans using a differential fear conditioning preparation. In this experiment, one neutral stimulus (conditioned stimulus; CS+) was paired with an aversive stimulus (unconditioned stimulus; US) during the acquisition phase, while another neutral stimulus was not (CS−). This procedure led to a difference in responding between the CS+ and the CS− (i.e., differential conditioning). After this acquisition phase, an extinction phase followed, during which both CSs were presented without the US, resulting in a decrease in differential conditioned responding. Reinstatement refers to the return of extinguished conditioned responses due to the experience of US-only trials after the extinction phase. This phenomenon was investigated by presenting half of the participants (reinstatement group) with unpredictable USs after the extinction phase. The control group did not receive these USs after the extinction procedure. The results show that return of fear was clearly apparent after the reinstating USs. This return of fear was, however, not limited to the CS+. An increase in ‘conditioned’ responding was also observed for the control stimulus. This interesting observation will be discussed against the background of a number of recent theoretical conceptualizations of reinstatement. 相似文献

It is important to understand racial/ethnic differences in adverse childhood experiences (ACEs), given their relationship to long-term physical and mental health, and the public health cost of the significant disparities that exist. Moreover, in order to inform interventions and promote resilience, it is critical to examine protective factors that mitigate the relationship between adversity and poor health. The current study utilized latent transition analyses (LTA) to examine co-occurring profiles of ACEs and protective factors (from school, family, and community contexts) and links to health outcomes among 30,668 Black (10.4%), Latinx (12.3%), and White youth (77.3%) ages 12–17 (52.5% male) who participated in the 2011–12 National Survey of Children's Health (NSCH). Results suggested that greater adversity was associated with worse health, while more access to protective factors was associated with better health. White youth had consistently lower endorsement of ACEs, greater access to protective factors, and better health compared to their Black and Latinx counterparts. Efforts to improve child health and racial/ethnic disparities in research and practice must consider adversity, protective factors, and the systemic inequities faced by racial/ethnic minority youth in the United States. 相似文献

Individuals encounter numerous examples of happy relationships in their social networks and through the media; however, it is unclear how comparisons to superior couples affect one's own relationship. We examined individuals' responses to upward relationship comparisons by exposing dating and married participants to highly successful relationships drawn from their own lives (Study 1) and an exemplar given to them (Studies 2–3). We predicted that moderately committed individuals would evaluate their relationship against the superior relationship, and consequently be less motivated to engage in relationship‐maintenance behaviors. In contrast, highly committed individuals would be inspired by the superior relationship and view their relationship more positively. Across all studies, higher commitment yielded more positive responses to upward relationship comparisons than did lower commitment. 相似文献

Previous research has shown that depressive rumination is an important vulnerability factor for experiencing depressive symptoms.
The most widely used measure to assess depressive rumination is the Ruminative Response Scale (RRS). According to Treynor
et al. (Cognitive Therapy and Research 27:247–259, 2003), the RRS contains two subscales, reflecting two different rumination subcomponents: brooding and reflection. The present
study examined the psychometric properties of the RRS in two samples (N = 432 and N = 407). Based on a confirmatory factor analysis (CFA), results confirmed that a two-dimensional model with brooding and reflection
factors provided an adequate fit to the data. Reliability, convergent and discriminant validity of the rumination subcomponents
were appropriate. Furthermore, brooding but not reflection predicted depressive symptoms prospectively, even when accounting
for concurrent depressive feelings. The results provide the first confirmatory factor-analytical support for the widely assumed
two-factor model of the RRS and add to the accumulating body of evidence supporting the multidimensional nature of depressive
rumination. 相似文献

Semantic interference effects in the picture—word interference (PWI) paradigm have long been assumed to reflect competitive
mechanisms during lexical selection, a core component of the speech production system. However, recent observations of facilitative
effects have cast doubt on the usefulness of the paradigm for investigating lexicalization, and on the existence of lexical
competition in general. An alternative proposal suggests that lexical selection is not by competition, and that interference
effects reflect articulatory processes outside the lexical system. Here, we contrast these theoretical alternatives with semantic
distractor effects in the PWI paradigm. In two tasks, pictures were either overtly named or the names were manually classified.
Interference effects of comparable magnitude were observed in both response modalities, regardless of whether the names were
articulated or not. This finding supports lexical competition models and suggests that the articulators are not the source
of interference in the PWI paradigm. Supplemental materials for this article may be downloaded from http://pbr.psychonomic-journals.org/content/supplemental. 相似文献

Cue-induced craving is not easily reduced by an extinction or exposure procedure and may constitute an important route toward relapse in addictive behavior after treatment. In the present study, we investigated the effectiveness of counterconditioning as an alternative procedure to reduce cue-induced craving, in a nonclinical population. We found that a cue, initially paired with chocolate consumption, did not cease to elicit craving for chocolate after extinction (repeated presentation of the cue without chocolate consumption), but did so after counterconditioning (repeated pairing of the cue with consumption of a highly disliked liquid, Polysorbate 20). This effect persisted after 1 week. Counterconditioning moreover was more effective than extinction in disrupting reported expectancy to get to eat chocolate, and also appeared to be more effective in reducing actual cue-elicited chocolate consumption. These results suggest that counterconditioning may be more promising than cue exposure for the prevention of relapse in addictive behavior. 相似文献

In the present study, sensory preconditioning of human electrodermal activity was demonstrated. In the first phase of the experiment, two pairs of neutral pictures of human faces were presented (A/B and C/D) sequentially. In the second phase, one picture of one pair was immediately followed by an electrocutaneous stimulus (B+), and one picture of the other pair was not (D-). In the third phase the other picture of each pair (A and C) was tested. The effect of A and C alone presentations (pre-extinction) between the first and the second phase was investigated. When only those participants that showed reliable B+/D- differentiation were considered, the extinction group did not show stronger conditioned electrodermal activity to A than to C, whereas the control group did. These findings suggest that sensory preconditioning of anticipatory/preparatory responding only occurs when the pre-conditioned stimulus (A) actually predicts the conditioned stimulus (B). 相似文献
