Two studies compared the relative strength of motivational assumptions drawn from SIT (e.g. Tajfel, 1978) and memory-based assumptions drawn from the differential familiarity hypothesis (Linville, Fischer and Salovey, 1989) in explaining ingroup bias and the black sheep effect (Marques, 1986, 1990). In Study 1, 15 subjects estimated member distributions and gave overall ratings of an ingroup and two outgroups. In Study 2, 42 subjects performed similar tasks for ingroup or outgroup, and evaluated likeable and unlikeable group members. Results showed, first, that overall group ratings account better for ingroup bias than do central tendencies of group distributions. In addition, likeable and unlikeable ingroup members were, respectively, upgraded and downgraded relative to their outgroup counterparts. Finally, whole ingroup ratings as well as judgements of likeable and unlikeable ingroup members proved more independent from variability and central tendency of underlying distributions than did similar outgroup judgements. Results are discussed in light of motivational and knowledge-based determinants of group judgements. 相似文献

This article contributes to different research traditions when proposes to reflect on theoretical fields, such as consumer culture and contemporary marketing. The study in a tourist and ecological conservation project revealed eco-restricted extraordinary experiences. We found a group of volunteers that build meanings and practices connected with new actions and habits that offer, not only ecological and sustainable benefits, but new value consumption relations. In contextualizing our findings, we highlight experiences and curiosities that are glossed over in academic and practical accounts that celebrate the extraordinary experience. It was observed, by analyzing data from various qualitative techniques, that the findings cross borders of mundane ingrained practices and bring an emerging domain, where both, consumption and anti-consumption experiences, offer insights into to a diversity of areas of knowledge. 相似文献

This paper reflects the working through of a group's fantasy that the deceased group leader wished the group to continue. As in any defense, the fantasy protected members from the pain of the finality of the leader's death. This article reveals the subjective experience concerning the effect of the leader's death on the group and members' intrapsychic struggle to separate and individuate from the deceased leader, while attending to and striving toward the group's continuation. The group's painful and growing individuation enabled the group to follow its own tasks without the spector of the deceased leader. 相似文献

Several studies have shown a negative linear relationship between speech rate and memory span. This relationship has implications for bilingual studies, as span could be larger in a bilingual's secondary language provided that pronunciation rate is faster than in the mother language. The purpose of this study was to investigate the effects of digit word length on digit span in bilinguals. Experiment 1 tested the effects of digit syllable length on speech rate in five different bilingual groups. Results revealed that digit-reading rates were significantly faster in all mother languages. Experiment 2 examined more closely the correspondence between speech rate and digit span with Portuguese-English bilinguals. Results showed that digit-reading rates were faster and digit span larger in the mother language even if the mean number of syllables per digit was higher. The superiority of mother tongue was discussed according to the view that digits are subject to massive practice in one's native language with a strong tendency to be abbreviated, thus reducing its spoken duration. 相似文献

The automatic skeletal motor responses of 20 male and 20 female student subjects (aged 20–36) receiving a painful stimulation (electric shock) were studied by examining voluntary concomitant extensions and flexions of the arm. These movements were either of long duration, allowing for an on-line control of their execution or, of short duration, requiring extensive pre-programming. Subjects were instructed either to push or to pull a lever upon receipt of an acoustic signal, which was paired or unpaired with an electric shock. Latencies for long duration movements (regardless of direction) were reduced by reception of painful stimulation. Latencies of short duration extensions and flexions were respectively reduced and increased by painful stimulation. Latencies of short duration movements were larger for females than males, regardless of movement direction. These data suggest that painful stimulation elicits automatic movements which affect programming of the termination of simultaneous voluntary movements. Implications of these findings for the study of aggressive behavior are discussed. © 1994 Wiley-Liss, Inc. 相似文献

Some well-known geometrical illusions disappear when the eyes are fixating and saccades are suppressed for a period of time. This disappearance is not accompanied by fading due to stabilisation of the retinal image. Any saccade made on purpose restores the illusion immediately. The fixation time after which some illusions disappeared was measured for four illusions and four subjects each. Effects of practice have been observed after measurements were repeated on successive days. Present theories of vision cannot readily explain the effect. 相似文献

Diagnostic tests are available to detect several mutations related to adult-onset, autosomal dominant, neurodegenerative diseases.
We aimed to describe our experience in a presymptomatic testing program run by the Brazilian Public Health System from 1999
to 2009. A total of 184 individuals were eligible for presymptomatic testing due to a risk for spinocerebellar ataxia (SCA)
- SCA3 (80%), Huntington’s disease (11.9%), familial amyloidotic neuropathy (4.3%), SCA1, SCA2, SCA6, or SCA7. Most were women
(70%), married (54%), and had children prior to presymptomatic testing (67%). Their mean age at entrance was 34 (SD = 11 years).
Educational level was above the average Brazilian standard. After receipt of genetic counseling, 100 individuals (54%) decided
to undergo testing; of these, 51 were carriers. Since no individual returned for post-test psychological evaluation, we conducted
a subsequent survey, unrelated to test disclosures. We contacted 57 individuals of whom 31 agreed to participate (24 had been
tested, 7 had not). Several ascertainment concerns relating to these numerous losses prevented us from generalizing our results
from this second survey. We concluded that: decision-making regarding presymptomatic testing seems to be genuinely autonomous,
since after genetic counseling half the individuals who asked for presymptomatic testing decided in favor and half decided
against it; general characteristics of Brazilians who sought presymptomatic testing were similar to many European samples
studied previously; and individuals at risk for SCA3 may be at greater risk of depression. Although no clear-cut reason emerged
for rejection of follow-up psychological sessions after presymptomatic testing, this finding suggests adjustments to our presymptomatic
testing program are necessary. 相似文献

The objective was to validate Regulatory Sensory Processing Disorders’ criteria (DC:0-3R, 2005) using empirical data on the presence and severity of sensory modulation deficits and specific psychiatric symptoms in clinical samples. Sixty toddlers who attended a child mental health unit were diagnosed by a clinical team. The following two groups were created: toddlers with RSPD (N?=?14) and those with “other diagnoses in Axis I/II of the DC:0-3R″(OD3R) (N?=?46). Independently of the clinical process, parents completed the Infant Toddler Sensory Profile (as a checklist for sensory symptoms) and the Achenbach Behavior Checklist for ages 1?–5 (CBCL 1?–5). The scores from the two groups were compared. The results showed the following for the RSPD group: a higher number of affected sensory areas and patterns than in the OD3R group; a higher percentage of sensory deficits in specific sensory categories; and a higher severity of behavioral symptoms such as withdrawal, inattention, other externalizing problems and pervasive developmental problems in CBCL 1?–5. The results confirmed our hypotheses by indicating a higher severity of sensory symptoms and identifying specific behavioral problems in children with RSPD. The results revealed convergent validity between the instruments and the diagnostic criteria for RSPD and supported the validity of RSPD as a unique diagnosis. The findings also suggested the importance of identifying sensory modulation deficits in order to develop an early intervention to enhance the sensory capacities of children who do not fully satisfy the criteria for some DSM-IV-TR disorders. 相似文献
