Speeded detection and increased distraction in fear of spiders: evidence from eye movements

Anxiety patients exhibit attentional biases toward threat, which have often been demonstrated as increased distractibility by threatening stimuli. In contrast, speeded detection of threat has rarely been shown. Therefore, the authors studied both phenomena in 3 versions of a visual search task while eye movements were recorded continuously. Spider-fearful individuals and nonanxious control participants participated in a target search task, an odd-one-out search task, and a category search task. Evidence for disorder-specific increased distraction by threat was found in all tasks, whereas speeded threat detection did not occur in the target search task. The implications of these findings for cognitive theories of anxiety are discussed, particularly in relation to the concept of disengagement from threat.     

A token reinforcement program in a public school: a replication and systematic analysis

A base rate of disruptive behavior was obtained for seven children in a second-grade class of 21 children. Rules, Educational Structure, and Praising Appropriate Behavior while Ignoring Disruptive Behavior were introduced successively; none of these procedures consistently reduced disruptive behavior. However, a combination of Rules, Educational Structure, and Praise and Ignoring nearly eliminated disruptive behavior of one child. When the Token Reinforcement Program was introduced, the frequency of disruptive behavior declined in five of the six remaining children. Withdrawal of the Token Reinforcement Program increased disruptive behavior in these five children, and reinstatement of the Token Reinforcement Program reduced disruptive behavior in four of these five. Follow-up data indicated that the teacher was able to transfer control from the token and back-up reinforcers to the reinforcers existing within the educational setting, such as stars and occasional pieces of candy. Improvements in academic achievement during the year may have been related to the Token Program, and attendance records appeared to be enhanced during the Token phases. The Token Program was utilized only in the afternoon, and the data did not indicate any generalization of appropriate behavior from the afternoon to the morning.     

Safari to masking land: A hunt for the elusive U

Due to the theoretical interest in whether U-shaped visual masking functions are obtained when discrimination responses are required of the Ss, an attempt was made to replicate the Weisstein and Haber (1965) experiment. The attempt was unsuccessful. The results indicated that masking was uniform over a temporal range of approximately 50 msec. The possibility of individual differences in the shape of masking functions was investigated in two subsequent experiments with negative results. Overall, the results of the three experiments supported a temporal integration account of masking when assessed by detection or discrimination criteria. Some possible reasons for discrepancies with the Weisstein and Haber (1965) experiment were considered.     

Effects of jet engine noise and performance feedback on perceived workload in a monitoring task

This study examined the effects of exposure to intermittent jet aircraft noise (70 dBA or 95 dBA maximum intensity) and knowledge of results concerning signal detections (hit-KR) on performance efficiency and perceived workload in a 40-min visual vigilance task. The noise featured a Doppler-like quality in which planes seemed to approach from the monitor's left and recede to the right. Perceptual sensitivity (d') was poorer in the context of noise than in quiet but only in the presence of hit-KR. The lack of noise-related performance differences in the absence of hit-KR most likely reflected a "floor effect" rather than some special relation between noise and feedback. When compared to subjects performing in quiet, those who operated in noise were less able to profit from hit-KR, a result that may reflect the effects of noise on information processing. In addition to its negative effects on signal detectability, noise elevated the perceived workload, as measured by the NASA-TLX. This effect was robust; it was independent of the presence of hit-KR, even though hit-KR generally lowered the overall level of perceived workload. The results provide the initial experimental demonstration that perceived workload is a sensitive measure of the effects of aircraft noise in monitoring tasks.     

Beholding the beholder: The reception of “Dutch” painting

While a lucid and understandable interpretation can be given for most pictures, typically Dutch paintings (i.e. seventeenth-century genre and still-life pictures) seem to allow for or even demand some measure of freedom for the beholder. The cause of this ambiguity lies in the typically Protestant disregard for works of art and in a concomitant characteristic of these works: they address the viewer in an ethical manner.In memoriam Sixten Ringbom, 1935-1992     

The effect of subliminal oedipal and competitive stimulation on dart throwing: another miss

Silverman and his associates have reported that subliminal presentation of oedipally relevant competitive stimuli can modify dart-throwing performance in male subjects. This study replicated their paradigm, but also examined the effects on performance of nonoedipal competitive stimuli. Our results failed to support Silverman's. Both types of subliminally presented competitive stimuli failed to have any systematic effect on dart-throwing performance.     

EVALUATION OF ATTITUDE SURVEY TRANSLATIONS: AN INVESTIGATION USING ITEM RESPONSE THEORY

The fidelity of a translated survey instrument used to measure attitudes toward mental health was evaluated using statistical methods based on item response theory. Data from French and German versions of the attitude survey were analyzed, and items that displayed differential item functioning (dif) were identified. Item characteristic curves (ICCs) were examined to determine whether the source of dif could be attributed to errors in translation or differences in cultural experiences or knowledge. The proposal by Humphreys and Hulin for using ICCs to determine the source of dif is evaluated.     

Attitudes and behavior: An information integration perspective

The relationship between attitudes, beliefs, and behavior was investigated in the context of a behavioral alternative model of attitudes and Anderson's information integration theory. Forty teenagers indicated their attitudes toward using each of seven methods of birth control. The attitudes were used to predict self-reports of contraceptive behavior. Functional measurement methodology was applied to understand the informational bases of the attitudes. In general, the data were supportive of the theoretical framework.     

Personalized versus standard role plays in the assessment of depressed patients' social skill

Chronically depressed outpatients participated in a study of the role-play assessment of social skill. Patients role-played a series of standard situations typical of those employed in social-skills research and additional scenes drawn from critical situations in their personal lives. These “personalized” role-play situations were perceived as more relevant by patients and resulted in more discomfort and less skillful interpersonal behavior than standard scenes. Behavioral measures derived from personalized role plays were also found to be more strongly related to measures of depression than the same measures derived from the standard role-play scenes. Implications of these findings for the role-play assessment of social skill are discussed.     

Parceling Cannot Reduce Factor Indeterminacy in Factor Analysis: A Research Note

Parceling—using composites of observed variables as indicators for a common factor—strengthens loadings, but reduces the number of indicators. Factor indeterminacy is reduced when there are many observed variables per factor, and when loadings and factor correlations are strong. It is proven that parceling cannot reduce factor indeterminacy. In special cases where the ratio of loading to residual variance is the same for all items included in each parcel, factor indeterminacy is unaffected by parceling. Otherwise, parceling worsens factor indeterminacy. While factor indeterminacy does not affect the parameter estimates, standard errors, or fit indices associated with a factor model, it does create uncertainty, which endangers valid inference.
