Blindfold chess is played without the players seeing either the pieces or the board. It is a skill‐related activity, and only very skilled players can construct the mental images required. This is why blindfold chess provides a good task with which to investigate the spatial memory and skilled mental images of expert players. In a PET investigation, we compared memory performance and problem solving in very experienced chess players with their performance in an attention task, in which the subjects classified the names of chess pieces. The memory task predominantly activated the temporal areas, whereas problem solving activated several frontal areas. The relevance of these findings to concepts such as general imagery, skilled imagery, apperception, and long‐term working memory are discussed.  相似文献

Through a review of the literature, this paper proposes arguments in favour of a multimodal, dynamic, functional, and situational conception of memory. Memory is assumed to contain traces that reflect past experiences. The properties of these experiences are considered to be distributed across multiple neuronal systems, which are responsible, in particular, for sensorimotor and emotional processing. Memory is dynamic because knowledge emerges almost continuously from the activation and integration of these multimodal components. Memory is functional and situational because knowledge emerges from the subject's activity in a given situation, that is from a type of resonance between the properties of the past experiences that have shaped the neuronal networks and the properties of present experiences.  相似文献

We explore familiarity-based recognition using a paradigm devised by Parkin et al. (2001). The task consists of the creation of two lists of words written with one of two different subsets of letters of the alphabet. We manipulated study time (50, 100, 200, 500 ms per word) of words with different letter probabilistic structure to those originally used by Parkin et al. Letter-based familiarity responding was robust and present even at rates producing otherwise chance performance. A second experiment and structural equation modelling led us to interpret the results from the point of view of a theory that takes into account the processing of similarities and differences (Hunt & MacDaniel, 1993). Finally, our data indicate that the experimental procedure devised by Parkin et al. is an excellent tool with which to study familiarity, once the structure of probabilities of individual letters is considered as the key factor in inducing the effect.  相似文献

The present study investigated how writing processes are activated during pause and execution periods. In two experiments, handwriting demands were manipulated by asking participants to compose with their familiar handwriting or with a high-demanding cursive uppercase calligraphy. Experiment 1 investigated narrative writing, a task with low planning demands. Experiment 2 addressed essay writing, a task with stronger planning demands. Occurrences of processes and their cognitive effort were analysed by asking participants to respond to random auditory probes and then to report their ongoing mental activity according to learned categories referring to the planning, translating, and revising writing processes. All together, the findings indicate that demands on planning did not affect how writing processes were activated during pauses and execution periods but automaticity of handwriting did. When handwriting was effortless, translating was mostly activated in parallel with motor execution, whereas revising and planning were mainly activated during pauses. However, none of the writing processes could be characterised as being typical of pauses, since translating was activated to a similar extent as the other two processes. By contrast, when handwriting was effortful, participants shifted to a more sequential functioning and activated translating mainly during pauses.  相似文献

Abstract

Operant choice theories pose that behavior distribution between options is ruled by the consequences related with these options. Evidence suggests that rats’ performance is attuned to the affordances that the operant setting provides, such as lever height. Our aim was to explore in rats whether lever press distribution was influenced by the affordances furnished by two levers. Lever pressing was reinforced in two concurrent equal variable-ratio schedules of reinforcement, and in successive conditions lever height was varied asymmetrically—that is, one lever was higher than the other. Results showed a quadratic relation between response rates and lever height, a linear trend between preference and lever height, and higher between- and within-bout response rates on the lower lever in four out of the six pairs of lever heights assessed. These findings suggest that intermediate lever heights favored lever pressing with faster bout initiation and faster within-bout responding, and support the idea that preorganized properties of behavior (i.e., the organism’s abilities) interact with the environment before the operant contingency takes place.  相似文献

In this study we examine whether components of spiritual transcendence can explain individual differences in mental health in a Hungarian adult sample (N = 583), with a special focus on the associations in two subsamples, religious professionals and psychotherapists. Using the Spiritual Transcendence Scale (STS), we found that religious professionals presented higher Prayer Fulfillment and Universality than psychotherapists; however, members of both professional groups scored higher than other professionals on these dimensions. By contrast, psychotherapists were superior to religious professionals in Connectedness. Moreover, higher Universality predicted better mental health, even after controlling for gender, age, profession, and basic personality traits. No interaction effects were found between profession and the subscales of the STS. Results suggest that the potential mental health benefits of spirituality, especially in form of a universal view of existence, are equally present in both specific professions and in the general sample, whereas the professions themselves still reflect differences both in spirituality and in well-being.  相似文献

This study examines the process of communicating BRCA1/2 genetic test results to family members, and the factors influencing disclosure. Twenty-nine semi-structured telephone interviews with BRCA1/2 tested individuals, 4 to 9 years post-notification, were conducted. Our results suggest that individual, familial, relational and socio-medical factors influence the decision to disclose/not disclose genetic test results to family members. These factors are at play in all three communication phases: the Decision-making phase, in which the individual ponders various factors before deciding to disclose test results to family members; the Disclosure phase, in which communication per se takes place; and the Reaction phase, which shapes the participant’s subsequent disclosure/non-disclosure decisions. We propose a guiding framework to assist in identifying and evaluating significant factors that might shape the course and outcome of the transmission of genetic information to family members.  相似文献

ABSTRACT

Background and Objectives: Super Skills for Life (SSL) is a transdiagnostic protocol based on cognitive–behavioral therapy designed for children with internalizing problems. The present study examined for the first time the impact of the Spanish-adapted version of SSL in reducing anxiety and depressive symptoms in Spanish-speaking children.

Design: A quasi-experimental design with one group, pre- and posttest, and 1-year follow-up was conducted. Analyses were performed on an intent-to-treat basis.

Methods: Participants were 119 children (42.9% female; 8–12 years) recruited from nine schools. Children completed assessments of anxiety, depression, emotional and behavioral difficulties, and the extent to which anxiety interfered with life before and after receiving the 8-session SSL, and 12-months post-intervention.

Results: Anxiety and depressive symptoms were significantly reduced at post-test and 12-month follow-up assessments. SSL also had positive impact on other symptoms assessed (e.g., interference of anxiety with children’s life, peer problems, conduct problems). Overall, the long-term benefits of SSL appeared to be greater than the short-term benefits.

Conclusions: The results of this study suggest that SSL may be useful in reducing symptoms of anxiety and depression, and a broad range of other issues, in Spanish children.  相似文献

Abstract

The present study examined the relationship between feelings provoked by child sexual abuse (CSA) and posttraumatic stress disorder (PTSD) symptom scores in a sample of 163 female survivors of CSA. Finkelhor and Browne's traumagenic dynamics model was applied. The interactive effects of provoked feelings with perpetrator age and the existence of abuse disclosure were also studied. Results showed an overall relationship between feelings provoked by CSA and PTSD symptom scores. Feelings of stigma, betrayal, and powerlessness as a result of CSA were associated with PTSD symptom score when the entire group of CSA victims was analyzed. The role of traumatic sexualization was relevant only when analyzed in interaction with the age of the perpetrator and disclosure. The relationship between traumatic sexualization and PTSD symptom scores was only significant when the abuse was committed by an adult perpetrator and when a disclosure was made during the time of abuse, or a short time after the abuse had occurred.  相似文献
