Experimental efforts to meliorate the modality effect have included attempts to make the visual stimulus more distinctive. McDowd and Madigan (1991) failed to find an enhanced recency effect in serial recall when the last item was made more distinct in terms of its color. In an attempt to extend this finding, three experiments were conducted in which visual distinctiveness was manipulated in a different manner, by combining the dimensions of physical size and coloration (i.e., whether the stimuli were solid or outlined in relief). Contrary to previous findings, recency was enhanced when the size and coloration of the last item differed from the other items in the list, regardless of whether the “distinctive” item was larger or smaller than the remaining items. The findings are considered in light of other research that has failed to obtain a similar enhanced recency effect, and their implications for current theories of the modality effect are discussed. 相似文献

Some data suggest that, as in explicit serial learning, longer sequences are more difficult to learn implicitly. These findings have been used to support the inference that implicit learning is capacity-limited. However, investigations of the effect of sequence length on implicit learning have confounded sequence structure with sequence length. These factors were manipulated independently in 3 experiments using a serial reaction time task. The results showed that sequence structure, not sequence length, largely determines the extent of sequence learning. 相似文献

The construct of alexithymia encompasses the characteristics of difficulty identifying feelings, difficulty describing feelings, externally oriented thinking, and a limited imaginal capacity. These characteristics are thought to reflect deficits in the cognitive processing and regulation of emotions and to contribute to the onset or maintenance of several medical and psychiatric disorders. In this article, we review recent methods for assessing alexithymia and examine how assessing alexithymia can inform clinical practice. Alexithymia is associated with heightened physiological arousal, the tendency to notice and report physical symptoms, and unhealthy compulsive behaviors. Alexithymic patients may respond poorly to psychological treatments, although perhaps not to cognitive-behavioral techniques, and it is unclear whether alexithymia can be improved through treatment. Interpretive problems regarding alexithymia include its overlap with other traits, whether it is secondary to illness or trauma, the possibility of subtypes, and low correlations among multiple measures. Nonetheless, we encourage the assessment of alexithymia in applied settings. 相似文献

The financial implications of the increased prevalence of autism, though rarely discussed, will be extremely important to
society. We compared the costs associated with 18 years of special education to the costs associated with the implementation
of an average of 3 years of Discrete Trial Training as an Early Intensive Behavioral Intervention (EIBI) in an effort to minimize
the need for special education. Our results indicate that the state of Texas would save $208,500 per child across eighteen
years of education with EIBI. When applied to the conservative estimate of 10,000 children with autism in Texas, the State
would save a total of $2.09 billion with EIBI. Implications for taxpayers, policymakers, and treatment are discussed. 相似文献

Taking a bright view of negative priming in the light of dim stimuli: further evidence for memory confusion during episodic retrieval. 总被引:3,自引:0,他引:3
A same-different letter-matching task was used to examine the effects of stimulus intensity on negative priming, which is poorer performance when target letters have been presented as distractor letters on the immediately preceding trial. In Experiment 1, stimulus intensity was manipulated between-participants, whereas in Experiment 2, it varied randomly from trial-to-trial within-participants. In Experiment 1, negative priming was equivalent for both stimulus intensities. In Experiment 2, negative priming effects were larger for repeated intensity stimuli than for nonrepeated intensity stimuli, when stimulus intensity was dim. Furthermore, for repeated intensity stimuli, negative priming effects were enhanced when the overt response required to the stimulus was repeated from prime to probe trial. These results are consistent with the hypothesis that negative priming may be due to memory confusion, rather than to inhibition of the distractor stimuli. 相似文献

Based on the concept of central sensitisation, the present study tested the hypothesis of comorbidity in allergic asthma and allergic rhinitis with diagnoses of functional somatic syndromes (FSSs), including fibromyalgia, irritable bowel syndrome and migraine. Data were used from the population-based Västerbotten Environmental Health Study (n = 3406). The participants consisted of 164 individuals with allergic asthma and 298 individuals with allergic rhinitis as well as 2876 individuals without allergic or non-allergic asthma, allergic rhinitis or atopic dermatitis. Diagnoses were based on self-reports of having been diagnosed by a physician. Odds ratios (ORs) were calculated from binary logistic regression analysis, both crude and adjusted for age and education. The adjusted ORs (1.87–4.00) for all FSSs differed significantly from unity for both allergic asthma and rhinitis. The results provide support for the hypothesis of comorbidity in allergic asthma and rhinitis with FSSs. Since central sensitisation is likely to underlie FSSs, the present findings raises the question as to whether central sensitisation may also be involved in allergic asthma and rhinitis. 相似文献

In a temporal order judgment task, in which observers select which of two words appeared first, Stolz (1999) found that observers
were more likely to select the word that had been semantically primed. Using repetition priming, we replicated Stolz’s finding
and extended her results by demonstrating that the effect was due to both (1) repetition priming causing the primed item to
be perceived as having occurred earlier and (2) a response bias to guess the repetition primed item as the correct response.
We discuss our new finding that priming induces an attentional precedence effect in the context of previous research suggesting
that exogenous spatial cuing induces an attentional precedence effect but identity or semantic priming may not. 相似文献

In three experiments, we explored the revelation effect in a frequency judgment task. Participants estimated the frequency of words that had been presented one, two, four, or eight times. At test, half the words were revealed by completing word fragments, and half were presented intact. Estimated frequencies were reliably higher for revealed than for intact words, and in two of the three experiments, the revelation effect became larger as actual frequency increased. A revelation effect was obtained whether the revealed word was the same as (Experiment 1) or different from (Experiment 2) the word judged for frequency. Frequency estimates were higher for more distorted test items (Experiment 3). 相似文献

It is important to understand how people with exhaustion disorder (ED) perceive interventions aiming to facilitate cognitive functioning. Therefore, the overall aim of this study was to explore experiences from persons with ED after participating in a 12-week intervention of either computerized cognitive training or aerobic training. Both interventions were performed in addition to a multimodal rehabilitation programme. Thirteen participants, 11 women and 2 men, were interviewed about pros and cons with participating in the training. The interviews were analysed with Qualitative Content Analysis. The analyses resulted in the theme hopeful struggling for health and the categories support, motivation and sensations. It was hard work recovering from ED. Support from others who are in the same situation, family members, and technology and routines for the training were strongly emphasized as beneficial for recovery. Timing, i.e., matching activities to the rehabilitation programme, getting feedback and perceiving joy in the training were important for motivation. Participants in both interventions experienced positive sensations with improved memory performance, everyday life functioning and increased faith in the prospect of recovery. However, it is important to consider various aspects of support and motivation in both computerized cognitive training and aerobic training to enable participants to pursue their participation. 相似文献
