Masking of a pure tone by a cubic difference tone or band generated by two pure tones or by a pure tone and a narrow band of noise as a function of the level of the masker was measured for three subjects at three ratios of f2/f1, 1.125, 1,2, and 1.3. The three maskers used were f1 alone, f1 + f2, and f1 + NBN (60-Hz band of noise centered at f2). At ratio 1.125, the amounts of masking produced by f1 alone and f1 + NBN were not significantly different for all subjects. For ratios = 1.125 and 1.2, f1 + f2 produced the least masking at least in two of the subjects. f1 + NBN was the best masker at ratios 1.2 and 1.3. These results show that the masking data on cubic difference tone at very small ratios of f2/f1 are not reliable due to the masking effect contributed by f1. For higher ratios, the combination band has to be used instead of combination tone because of the interaction between the signal and the cubic difference tone. Also the divergence of the effectiveness in masking by the three maskers gives an estimation of the levels of primaries at which the cubic difference tone is generated. 相似文献

In 3 studies, the idea was tested that an increase in a police officer's movements in an interview will lead to an increase in movements made by the suspect. This increase in movements may then be interpreted by the police officer as suspicious behavior. In Study 1, interviewees were interviewed by 1 male police officer who either made some movements or no movements at all. The movements made by the suspects were investigated. In Studies 2 and 3, police officers were asked to judge the credibility of interviewees who were interviewed by a lively or a nonlively interviewer. The results supported the process described. 相似文献

Possible differences in social comparison choices between individualistic and collectivistic cultures and individuals were
explored among a sample of 235 student participants from the United States and China, focusing on self-esteem as a possible
mediating variable. A self-report social comparison measure was developed and factor analyzed. Correlations revealed that
higher collectivism scores were associated with an increased desire to compare in general, an increased desire to make upward
comparisons, and a decreased desire to make downward comparisons. It is speculated that upward self-improvement comparisons
for the sake of the group may be more common for those high in collectivism. 相似文献

The space-time accuracy of an elbow flexion movement task was examined in two experiments over a range of motion extents (1 degrees through 100 degrees ) and short-duration movement times (100, 125, 150, and 400 ms). Nonlinear speed-accuracy functions emerged for both spatial and temporal error over all the movement conditions examined. The results showed that the timing error and spatial error had a high degree of complementarity as predicted by a space-time model of the speed-accuracy relation (Hancock & Newell, 1985). The findings confirm that the frame of reference for measuring movement error determines in part the error functions observed. 相似文献

The offender profiling process is an investigative technique used to identify the major personality and behavioural characteristics of the offender based upon an analysis of the crime(s) he or she has committed (Douglas & Burgess, 1986). Attempts have been made in both England and America to classify rapists into various subgroups. Instead of definitive groups of offenders a suggestion is made as to the formation of a dimensional typology of rapists. This would allow for the difficulties in defining boundaries for subgroups and accounting for individual differences and heterogeneity of both the rapist and the assault. The various criteria that attempt to distinguish the different types of offender are discussed including behavioural and motivational characteristics of the offender, lay theories of rape and the victim-offender relationship. The implications of the dimensional typology are outlined. There are indications that some factors may contribute to a longer and more complicated recovery process. Macnab (1993) neatly outlines eleven contributory factors: financial stress, various long term stresses, the degree of violence, the use of weapons, the sense of violation, the threat of death, multiple assailants, threats of greater or continuing harm and a later death, medical complications, problems with police, medical and criminal systems and lack of adequate professional and informed support. As well as this, the important issue of self-blame is discussed along with the subsequent problem of post-traumatic stress disorder: the recurring distressing memories, dreams and events and signals that can provoke a further cycle of distress. 相似文献

Many people experience estrangement from a family member, which is broadly understood to refer to negative relationships that are characterised by little or no contact. However, little is known about how people cope with family estrangement. To address this gap, interviews were conducted with 46 participants who identified as being estranged from a parent/sibling and/or child and having sought therapeutic support for this experience. The participants were recruited from a UK-based charity that supports individuals experiencing family estrangement. The participants had a range of experiences of therapeutic support, with most (N = 31, 67%) having paid for private therapy. The data were analysed using thematic analysis, and three themes were generated: (1) finding the missing qualities in estranged family relationships: warmth, validation and safety; (2) speaking the unspoken: addressing the causes and consequences of estrangement; and (3) learning relational skills: improving the relationship with oneself and with others. When the causes of estrangement were addressed in the context of a safe therapeutic relationship, participants learned strategies to improve the relationships they had both with themselves and with others. When participants experienced a cold or unresponsive therapeutic relationship, and the causes and consequences of estrangement were not adequately addressed or understood, counselling was experienced as unhelpful. Individuals who seek therapeutic support for family estrangement have specific needs. Training around these needs and the causes and consequences of estrangement could be beneficial to helping professionals and the clients with whom they work. 相似文献

In the present study it was investigated to what extent observers (i) could make rapid yet reliable and valid judgements of the frequency of verbal and nonverbal behaviours of interviewees (liars and truth tellers) and (ii) detect deceit after making these rapid judgements. Five observers watched 52 videoclips of 26 liars and 26 truth tellers. The findings revealed that rapid judgements were reliable and valid. They also revealed that observers were able to detect truths and lies well above the level of chance after making these rapid judgements (74% accuracy rate was found). The implications of these findings for deception researchers and lie detection are discussed. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

This study investigated what effect a 30% oxygen administration had on visuospatial cognitive performance and cerebral activation and lateralization using fMRI. Eight college students were selected as the subjects for this study. An oxygen dispenser that provided 21% and 30% oxygen at a constant rate of 8L/min was developed. In order to measure the performance level of visuospatial cognition, two psychological tests were also developed. The experiment consisted of two runs, one for a visuospatial cognition task with normal air (21% oxygen) and the other for a visuospatial cognition task with hyperoxic air (30% oxygen). Functional brain images were taken with a 3T MRI using the single-shot EPI method. The results of the visuospatial behavioral analysis reveal that accuracy rates were enhanced with 30% oxygen administration when compared to 21% oxygen. There were more activations observed at the bilateral occipital, parietal, and frontal lobes with 30% oxygen administration. However, decreased cerebrum lateralization was observed with 30% oxygen administration in the same regions compared with 21% oxygen administration. Thus, it is concluded that the positive effect on the visuospatial cognitive performance level by the highly concentrated oxygen administration resulted from an increase of cerebrum activation and a decrease of cerebrum lateralization. 相似文献

The reported prevalence rates of cyber victimization experiences and cyberbullying behaviors vary. Part of this variation is likely due to the diverse definitions and operationalizations of the constructs adopted in previous research and the lack of psychometrically robust measures. Through 2 studies, the authors developed (Study 1) and evaluated (Study 2) the cyber victimization experiences and cyberbullying behaviors scales. Participants in Study 1 were 393 (122 boys, 171 girls) and in Study 2 were 345 (153 boys, 192 girls) 11–15-year-olds who completed measures of cyber victimization experiences, cyberbullying behaviors, face-to-face victimization experiences, face-to-face bullying behaviors, and social desirability. The 3-factor cyber victimization experiences scale comprised threat, shared images, and personal attack. The 3-factor cyberbullying behaviors scale comprised sharing images, gossip, and personal attack. Both scales demonstrated acceptable internal consistency and convergent validity. 相似文献
