The verbal transformation effect: auditory illusions as an index of lexical processing and homolog activation.

A technique of inducing auditory illusions was used so that 192 undergraduates heard through headphones either three asynchronous dichotic versions of the same repeating word, at each of three auditory locations (left, center, and right), or only one single repeating word, monaurally or diotically, at each location. Independent illusory changes at each location were reported. Subjects' reports of lexical illusions, but not nonlexical illusions, were fewer at the right ear for three- vs. one-signal listening. These results support the homolog activation hypothesis (Boles, 1990) in which disruption of interhemispheric communication occurs for the hemisphere least capable of processing lexical information. In the current experiment homolog activation led to loss of lexical information when received from auditory positions other than the right, when three signals are presented. Lexical illusions (Verbal Transformations) may be the result of the misapplication of lexical knowledge in an ambiguous situation, listening to a recycling word without stabilizing syntactic or semantic context.     

Auditory habituation in young and older adults: the verbal transformation effect

In 3 experiments, auditory massed repetition was used to examine age-related differences in habituation by means of the verbal transformation paradigm. Participants heard 10 words (5 high frequency and 5 low frequency), each presented 180 times, and they reported perceived changes in the repeated words (verbal transformations). In these experiments, older adults reported fewer illusory percepts than young adults. Older adults' loss of auditory acuity and slowing of processing, stimulus degradation (in young adults), and instructions biasing the report of these illusory percepts did not account for the fewer illusory percepts reported by the older adults. These findings suggest that older adults' reduced susceptibility to habituation arises from centrally located declines in the transmission of information within the word-recognition pathway. The discussion focuses on the implications that these age-related declines may have on word identification during on-line speech perception.     

Children are cursed: an asymmetric bias in mental-state attribution

Abstract - Young children have problems reasoning about false beliefs. We suggest that this is at least partially the result of the same curse of knowledge that has been observed in adults—a tendency to be biased by one's own knowledge when assessing the knowledge of a more naive person. We tested 3- to 5-year-old children in a knowledge-attribution task and found that young children exhibited a curse-of-knowledge bias to a greater extent than older children, a finding that is consistent with their greater difficulty with false-belief tasks. We also found that children's misattributions were asymmetric. They were limited to cases in which the children were more knowledgeable than the other person; misattributions did not occur when the children were more ignorant than the other person. This suggests that their difficulty is better characterized by the curse of knowledge than by more general egocentrism or rationality accounts.     

Application of the verbal transformation effect with learning-disabled children

Verbal Transformations (VTs) are an illusory effect which results from hearing a tape recording consisting of one word repeated twice per second. VTs have been employed to ascertain auditory perceptual differences in normal subjects relative to chronological age. This research tested two groups of 10 male children (normal and learning disabled). Results showed a significant difference (p < .01) between the reported number of VTs per group, with normal subjects verbalizing more different words. LD results are compared to VT studies with geriatrics. A theory is presented to explain our findings based upon a defect in short-term memory.     

Transitory bias as a source of customer dissatisfaction: An exploratory investigation

Previous literature has identified sources of customer dissatisfaction in the forms of poor product performance, discrimination, and universal mistreatment (i.e., broad-based mistreatment of customers). This article proposes the existence of a fourth source of perceived customer dissatisfaction, termed transitory bias, which is based upon fleeting customer characteristics and actions. Using a critical incident approach, this exploratory study analyzes customer narratives of 230 negative experiences. After writing their narratives, consumer informants completed a quantitative survey pertaining to their experience. Some sources of transitory bias were found to be customer complaining, negotiation, special requests, and underpurchasing. Transitory bias was found to drive perceptions of negative customer experiences in 29.1 per cent of the narratives. This was fewer than the number of cases involving universal mistreatment (50%) but more than those involving poor product performance (18.3%) and discrimination (2.6%). Results showed that satisfaction, repeat purchase likelihood, recommendation likelihood, and word of mouth were similar to those found in narratives where universal mistreatment and discrimination were primary drivers of dissatisfaction. This article creates awareness of the transitory bias construct and allows academicians the opportunity to study it as a source of customer dissatisfaction. Retail and service establishments should be aware of customer perceptions of transitory bias because it impacts key performance metrics. Managers may wish to train employees to better identify and respond to sources of transitory bias. Copyright © 2013 John Wiley & Sons, Ltd.     

Experimental design as a source of sex bias in social psychology

In order to determine whether there is evidence for sex bias in experimental design, abstracts of 312 experiments on interpersonal attraction and 244 experiments on aggression which used only male or only female subjects were coded according to types of variables studied. Results indicate that when females are subjects in experiments the independent variable manipulation is less likely to involve the active treatment or arousal of the subject and the dependent variable measurement is less likely to involve the active behavior of the subject, than when male subjects are used. These findings are discussed in terms of their implications for how sex differences should be studied.Portions of this article were presented at the meeting of the American Psychological Association, New Orleans, September 1974. The authors would like to thank Howard Ehrlichman for his valuable comments.     

Focalism: a source of durability bias in affective forecasting

The durability bias, the tendency to overpredict the duration of affective reactions to future events, may be due in part to focalism, whereby people focus too much on the event in question and not enough on the consequences of other future events. If so, asking people to think about other future activities should reduce the durability bias. In Studies 1-3, college football fans were less likely to overpredict how long the outcome of a football game would influence their happiness if they first thought about how much time they would spend on other future activities. Studies 4 and 5 ruled out alternative explanations and found evidence for a distraction interpretation, that people who think about future events moderate their forecasts because they believe that these events will reduce thinking about the focal event. The authors discuss the implications of focalism for other literatures, such as the planning fallacy.     

Motherhood: a potential source of bias in employment decisions

Results of 2 experimental studies in which job incumbents were said to be applying for promotions to traditionally male positions demonstrated bias against mothers in competence expectations and in screening recommendations. This bias occurred regardless of whether the research participants were students (Study 1) or working people (Study 2). Although anticipated job commitment, achievement striving, and dependability were rated as generally lower for parents than for nonparents, anticipated competence was uniquely low for mothers. Mediational analyses indicated that, as predicted, negativity in competence expectations, not anticipated job commitment or achievement striving, promoted the motherhood bias in screening recommendations; expected deficits in agentic behaviors, not in dependability, were found to fuel these competence expectations. These findings suggest that motherhood can indeed hinder the career advancement of women and that it is the heightened association with gender stereotypes that occurs when women are mothers that is the source of motherhood's potentially adverse consequences.     

Valuing thoughts, ignoring behavior: The introspection illusion as a source of the bias blind spot

People see themselves as less susceptible to bias than others. We show that a source of this bias blind spot involves the value that people place, and believe they should place, on introspective information (relative to behavioral information) when assessing bias in themselves versus others. Participants considered introspective information more than behavioral information for assessing bias in themselves, but not others. This divergence did not arise simply from differences in introspective access. The blind spot persisted when observers had access to the introspections of the actor whose bias they judged. And, participants claimed that they, but not their peers, should rely on introspections when making self-assessments of bias. Only after being educated about the importance of nonconscious processes in guiding judgment and action—and thereby about the fallibility of introspection—did participants cease denying their relative susceptibility to bias.     

Acting or listening: Adult age differences in source recall of enacted and nonenacted statements

This study explored age-related differences in item and source recall of enacted and nonenacted items in a sample of healthy adults between the ages of 35 and 80 years (N=1,000). Participants were screened on a variety of demographic, psychometric, and biological variables. They were presented with sentences (e.g., Lift the book) that they either read or enacted. They were then asked to recall the object of each stimulus sentence (item recall) and to identify its format of encoding (source recall). Age-related decrements were observed both in item and source memory, although age differences in source memory were more accentuated than in item memory. Further, the results indicated an overall impairment of source memory across age when individual differences in the demographic, psychometric, and biological variables were taken into consideration.     

The bias in the bias: Comparative optimism as a function of event social undesirability

We present a new event-level predictor of comparative optimism: comparative optimism is larger for more socially undesirable events. A meta-analysis shows that event social undesirability predicts comparative optimism effect sizes reported in the literature, over and above the effects of other known predictors. Four experiments corroborate this finding and demonstrate the key role played by respondents’ impression management motives. The effect of social undesirability decreases with stronger than usual anonymity assurances, increases with greater impression management tendencies, and reverses when people want to make a negative impression. Because social undesirability is correlated to other known predictors of comparative optimism (e.g., controllability, severity), it is important to take its effects into account when assessing the effect of other event characteristics. The current research adds to, and bridges, the literatures on event-level predictors and impression management in comparative optimism.     

Acquiescence as a source of bias and model and person misfit: A theoretical and empirical analysis

In personality and attitude measurement, the presence of acquiescent responding can have an impact on the whole process of item calibration and test scoring, and this can occur even when sensible procedures for controlling acquiescence are used. This paper considers a bidimensional (content acquiescence) factor‐analytic model to be the correct model, and assesses the effects of fitting unidimensional models to theoretically unidimensional scales when acquiescence is in fact operating. The analysis considers two types of scales: non‐balanced and fully balanced. The effects are analysed at both the calibration and the scoring stages, and are of two types: bias in the item/respondent parameter estimates and model/person misfit. The results obtained theoretically are checked and assessed by means of simulation. The results and predictions are then assessed in an empirical study based on two personality scales. The implications of the results for applied personality research are discussed.     

Perceiver bias in the processing of deliberately asymmetric emotional expressions

Posers were requested to produce happy and sad emotional expressions, deliberately accentuated on the left and right sides of the face. Raters judged the emotional intensity of expressions when presented in original and mirror-reverse orientation. Left-side-accentuated sad expressions were rated as more intense than right-side-accentuated sad expressions. Raters were biased to judge expressions as more intense when the accentuated side was to their left. The findings indicated that the perceiver bias in weighting information from the side of the face in left hemispace extends to judgments of emotional intensity.
