A cue size procedure was used to evaluate the time course of visuo-spatial attention in dyslexic and normally reading children. When a stimulus target is presented inside a large cue vs a small cue the identification time is slower. In the present study two cue-target delays (100 and 500 ms) were used. Results showed a slower time course of attentional focusing in dyslexics vs normal readers. Indeed, dyslexics exhibited no cue size effect at a shorter cue-target delay (100 ms), while it was present at a longer cue-target delay (500 ms). In contrast, a cue size effect was found at both cue-target delays in normally reading children. These results further support the hypothesis of sluggish automatic focusing of visual attention in dyslexics. This impairment could be a consequence of a general magnocellular deficit demonstrated previously in dyslexics. 相似文献

Two studies were conducted to develop and examine internal consistencies and validate the Abbreviated Multidimensional Acculturation Scale. Study 1 participants were 156 Latino/Latina college students. Findings indicated good internal reliabilities for all 3 subscales. Adequate concurrent validity was established with length of residence in the United States. The scale also showed adequate convergent and discriminant validity. Study 2 participants were 90 Latino/Latina community members. The subscales were also reliable and showed adequate concurrent validity with length of residence in the United States. Convergent and discriminant validity were also adequate. Construct validity was further demonstrated through factorial analyses of the combined samples (N = 246). Three separate factors emerged: cultural identity, language competence, and cultural competence. 相似文献

This case study examines a pattern we believe to be common among female prostitutes: a woman (Bonnie) who, like most prostitutes, is a survivor of childhood sexual abuse. Bonnie's prostitution is part of the unconscious repetition compulsion common in trauma victims; by prostituting herself, Bonnie re-creates the scenario of sexual abuse that occurred during her childhood, while maintaining an illusion of control over the situation. We maintain that an effective approach to treatment for Bonnie is integrative therapy, a type of psychological counseling designed to address the major aftereffects of sexual abuse: dissociation from the body and sexuality in general; a profound sense of powerlessness; critically low valuation of the self; and mistrust and fear of intimacy. Bonnie's story shows the dynamics of both prostitute behavior and integrative therapy, providing an example we believe to be applicable far beyond this case study. 相似文献

Previous studies have shown that source identification (ID) tests reduce, and in some cases eliminate, eyewitness suggestibility errors. The present study showed that the suggestibility errors participants committed on a source ID test were further reduced when they were given the explicit postwarning that the experimenter was trying to trick them. These postwarnings reduced suggestibility to the same extent as prewarnings, and they did so for both once and repeatedly suggested items. In addition, the benefits of the pre- and postwarnings persisted when participants were retested 1 week later, but only if the suggestions had been repeated. For once-suggested items, the warning had the unintended effect of improving old/new recognition of the suggested information at retest, an effect that offset the improvements in source discrimination accuracy conferred by the warning. The advantages of using source ID tests for investigating group differences in eyewitness suggestibility are discussed. 相似文献

Patients with lesions to the right parietal lobe were tested on their ability to reach to targets, or to respond verbally to targets. The targets occurred at the same two spatial locations--to the left and right of the patient--with the task being cued by the color of the target. Patients were able to perform both tasks separately rapidly and without error. However, when the two tasks were interleaved, they had difficulty making a response in the left (contralesional) field when this was different to a response that they had just made. These results suggest that lesions to the parietal cortex may cause a deficit in the coding for motor intention, as well as attention in the contralesional field. 相似文献

Context-specificity of fear extinction was tested among 65 participants who were fearful of spiders by manipulating the contexts used for exposure treatment and two-week follow-up assessment. Context was defined by both meaningful (presence of a particular therapist) and incidental (room location and furnishings) environmental cues. Distinct phobic stimuli were used to examine interactions of context with stimulus. Physiological, behavioral and verbal indices of fear were measured. Results provided modest support for context-specific return of fear. With one stimulus, participants assessed in a non-treatment context at follow-up exhibited greater returns in heart rate levels. In addition, three of four participants who could not touch the stimulus at follow-up had been tested in a non-treatment context. Future investigations may benefit from greater distinctions between contexts or manipulation of contextual features more directly relevant to fear. Finally, post hoc analyses identified high trait anxiety, slow treatment response, recovery of phobic cognitions and long duration/high intensity phobic encounters post-treatment as significant predictors of increased return of fear. 相似文献

Four experiments investigated the effect of grammatical gender on lexical access in Russian. Adjective–noun pairs were presented auditorily, using a cued-shadowing technique in which subjects must repeat the second word (the target noun), following adjectives that are either concordant or discordant with the noun's gender. Experiment 1 demonstrates gender priming with unambiguous adjectives and phonologically transparent masculine or feminine nouns. Experiment 2 examines priming for transparent nouns against a neutral baseline (possible only for feminines and neuters), revealing that priming is due primarily to inhibition from discordant gender. Experiment 3 demonstrates gender priming with phonologically opaque masculine and feminine nouns. Experiment 4 returns to transparent masculine and feminine nouns with a different kind of baseline, using three versions of a single word root (prost—simple, in the feminine adjectival form prostaja, masculine adjectival form prostoj, and the adverbial form prosto ), and shows that gender can also facilitate lexical access, at least for feminine nouns. We conclude that Russian listeners can exploit gender agreement cues on-line, helping them to predict the identity of an upcoming word. 相似文献
