Response bias and Murdock's D scale.

Murdock's D scale predicts a U shaped curve of % correct identification as a function of the position of the stimulus. An inadequacy in the D scale was brought to light in an absolute judgment study by this author. Ss displayed a powerful response bias, avoiding end responses, when judging line lengths. A simple correction for such a response frequency imbalance is suggested, and with this correction the line-length data support the D scale approach to the quantification of distinctiveness.

A further study of the relationship between response bias and perceptual defense.

Ss were exposed to tachistoscopically-presented pairs of words and asked to report whether a particular word was on the left or right of a fixation point. A non-statistically-significant trend showed that Ss tended to demonstrate a response bias in terms of reporting anxiety or neutral words on one or the other side whether or not they were in fact on the stated side of the point. A 2nd phase of the experiment presented S with blank stimulus fields although S was expecting words. A response bias was not demonstrated. "… it is suggested that the use of a forced-choice spatial indicator of perception may undermine the motivational basis for perceptual defense."

Avoiding the approach trap: A response bias theory of the emotional Stroop effect.

In the laboratory, people classify the color of emotion-laden words slower than they do that of neutral words, the emotional Stroop effect. Outside the laboratory, people react to features of emotion-laden stimuli or threatening stimuli faster than they do to those of neutral stimuli. A possible resolution to the conundrum implicates the counternatural response demands imposed in the laboratory that do not, as a rule, provide for avoidance in the face of threat. In 2 experiments we show that when such an option is provided in the laboratory, the response latencies follow those observed in real life. These results challenge the dominant attention theory offered for the emotional Stroop effect because this theory is indifferent to the vital approach–avoidance distinction.

The Edwards SD scale: A short form of the MMPI?

Edwards has described a rationale for predicting MMPI scores based upon social desirability response bias. The clinical utility of this technique was examined by comparing the predicted average MMPI profile with the average profile actually obtained by college males. The estimated and actual profiles were markedly discrepant, indicating that Edwards' SD scale is not a useful substitute for the MMPI.

Rater reliability and the heterogeneity of scale anchors.

"Raters (N=200) used 5-category rating scales, which varied in the heterogeneity of the verbal anchors defining the end categories, to rate for preference value two lists of ten foods. The food lists differed in the homogeneity of food stimuli on each list. Measures of individual rater reliability and rater bias were computed and analyzed as to the effect of scale and list differences. Reliability was significantly smaller for the more homogeneous list and increased linearly as a function of the heterogeneity of the end anchors. Rater bias was unaffected by either scale or list differences." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Empathy neglect: Reconciling the spotlight effect and the correspondence bias.

When people commit an embarrassing blunder, they typically overestimate how harshly they will be judged by others. This tendency can seem to fly in the face of research on the correspondence bias, which has established that observers are, in fact, quite likely to draw harsh dispositional inferences about others. These seemingly inconsistent literatures are reconciled by showing that actors typically neglect to consider the extent to which observers will moderate their correspondent inferences when they can easily adopt an actor's perspective or imagine being in his or her shoes. These results help to explain why actors can overestimate the strength of observers' dispositional inferences even when, as the literature on the correspondence bias attests, observers are notoriously prone to drawing those very inferences.

Vignettes portrayed a male or a female client, and history of childhood sexual abuse was presented either first or last. Results indicated that cognitive–behavioral therapy (CBT) clinicians were more likely to diagnose PTSD than BPD or other disorders, and psychodynamic clinicians were more likely to diagnose BPD or other disorders than PTSD. An anchoring effect (i.e., evidence that one regards initial information as an anchor that may or may not be adjusted upon exposure to subsequent information) of abuse history presentation was found.

Proactive interference, accessibility bias, and process dissociations: Valid subject reports of memory.

Proactive interference was assessed with a variant of the process-dissociation procedure, which separates effects of habit (accessibility bias) and recollection (discriminability). In three cued-recall experiments, proactive interference was shown to be an effect of bias rather than an effect on actual remembering. Divided attention, age, and study duration selectively influenced the recollection parameter, whereas training probability selectively influenced the habit parameter. Furthermore, in Experiments 2 and 3, subjective reports of remembering were highly correlated with, and nearly identical to, objective estimates of recollection gained from the process-dissociation procedure. The authors discuss the relevance of the results to theories of proactive interference and argue that older adults' greater susceptibility to interference effects is sometimes caused by an inability to recollect rather than by an inability to inhibit a preponderant response.

Representing target motion: The role of the right hemisphere in the forward displacement bias.

Patients with left spatial neglect, patients with right hemisphere damage but no neglect, and a control group were asked to judge the final position of a series of moving targets. Both patient groups showed attentional deficits. All 3 groups demonstrated a forward displacement bias, overestimating the final target position along the object trajectory. However, in both patient groups the size of this forward displacement bias decreased as the distance the target traveled before vanishing increased. For horizontally moving targets, at the maximum distance only the control group showed significant forward displacement. For all 3 groups, the direction in which the target traveled had no influence, but the size of the forward displacement increased as target speed increased. Several attentional explanations of these results are considered, including the differential allocation of spatial attention between central and peripheral locations, differences between exogenous and endogenous attention, and deficits in sustained attention.

Acquiescent response set and the Psychasthenia scale: An analysis via the Aussage experiment.

An attempt was made to test the hypothesis that accuracy of testimony would be affected by the suggestibility of the observer, herein referred to as "acquiescent response set." The degree of potential acquiescence was measured by the Pt scale of the MMPI; the data gleaned from the classical example of distortion in recall of a staged event involving a classroom "stooge" and the instructor. Tested on 230 students in an introductory Psychology course, the hypothesis was sustained. From Psyc Abstracts 36:02:2HF19K. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The psyche in psychophysics: A sensory-decision theory analysis of the effect of instructions on flicker sensitivity and response bias.

Instruction-induced changes in flicker thresholds, measured by traditional psychophysical procedures, may reflect changes in sensory sensitivity or in response bias. In 16 psychiatric patients, a facilitating set, in contrast to an inhibiting set, increased the proportion of flicker responses to both a physically intermittent light ("hits," p     

Across the thin blue line: Police officers and racial bias in the decision to shoot.

Police officers were compared with community members in terms of the speed and accuracy with which they made simulated decisions to shoot (or not shoot) Black and White targets. Both samples exhibited robust racial bias in response speed. Officers outperformed community members on a number of measures, including overall speed and accuracy. Moreover, although community respondents set the decision criterion lower for Black targets than for White targets (indicating bias), police officers did not. The authors suggest that training may not affect the speed with which stereotype-incongruent targets are processed but that it does affect the ultimate decision (particularly the placement of the decision criterion). Findings from a study in which a college sample received training support this conclusion. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stereotype activation and control of race bias: Cognitive control of inhibition and its impairment by alcohol.

Two experiments tested the hypothesis that alcohol increases race-biased responding via impairment of self-regulatory cognitive control. Participants consumed either a placebo or alcohol and then made speeded responses to stereotypic trait words presented after White and Black face primes while behavioral and event-related brain potential (ERP) data were recorded. Alcohol did not affect stereotype activation in either experiment. Experiment 2 showed that alcohol significantly impaired the ability to inhibit race-biased responses but did not reliably influence control of counterstereotypic responses. This disinhibition appears driven by impairment of regulative cognitive control, as indexed by amplitude of the negative slow wave ERP component. These findings suggest that controlling racial bias can be a function of effective implementation of basic self-regulatory processes in addition to the motivational processes identified in other research.

Older but wilier: In-group accountability and the development of subjective group dynamics.

To test social and cognitive variables that may affect the development of subjective group dynamics, the authors had 224 children between the ages of 5 and 12 years evaluate an in-group and an out-group and normative and deviant in-group members under conditions of high or low accountability to in-group peers. In-group bias and relative favorability to normative versus deviant in-group members (differential evaluation) increased when children were accountable to peers and as a function of perceptions of peer group acceptance of these members (differential inclusion). These effects were significantly larger among older children. Multiple classification ability was unrelated to judgments of group members. This study shows that the development of subjective group dynamics involves an increase in sensitivity to the normative aspects of the intergroup context.

Differentiation and response bias in episodic memory: Evidence from reaction time distributions.

In differentiation models, the processes of encoding and retrieval produce an increase in the distribution of memory strength for targets and a decrease in the distribution of memory strength for foils as the amount of encoding increases. This produces an increase in the hit rate and decrease in the false-alarm rate for a strongly encoded compared with a weakly encoded list, consistent with empirical data. Other models assume that the foil distribution is unaffected by encoding manipulations or the foil distribution increases as a function of target strength. They account for the empirical data by adopting a stricter criterion for strongly encoded lists relative to weakly encoded lists. The differentiation and criterion shift explanations have been difficult to discriminate with accuracy measures alone. In this article, reaction time distributions and accuracy measures are collected in a list-strength paradigm and in a response bias paradigm in which the proportion of test items that are targets is manipulated. Diffusion model analyses showed that encoding strength is primarily accounted for by changes in the rate of accumulation of evidence (i.e., drift rate) for both targets and foils and manipulating the proportion of targets is primarily accounted for by changes in response bias (i.e., starting point). The diffusion model analyses is interpreted in terms of predictions of the differentiation models in which subjective memory strength is mapped directly onto drift rate and criterion placement is mapped onto starting point. Criterion shift models require at least 2 types of shifts to account for these findings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A meta-analytic investigation of the relationship between attentional bias and subjective craving in substance abuse.

Theoretical models of addiction suggest that attentional bias for substance-related cues should be associated with self-reported craving. The authors evaluated the strength of the association by performing a meta-analysis on 68 independent data sets from which correlation coefficients between subjective craving and attentional bias indices were derived. Additional stratified analyses were conducted to identify any variables that might moderate the association between craving and attentional bias. The primary meta-analysis indicated a significant, albeit weak (r = .19), association between attentional bias and craving. Stratified analyses revealed that the association was larger for illicit drug and caffeine craving than for alcohol and tobacco craving, larger for direct measures of attention (eye movement measures and event-related potential measures) than for indirect behavioral measures of attentional bias, and larger when craving strength was high than when it was low (all ps     

Substantive and operational issues of response bias across levels of analysis: An example of climate-satisfaction relationships.

Two studies tested whether method variance is present at multiple levels of analysis and whether methodological procedures can minimize its impact. In Study 1, 8,052 employees from 71 hotels completed measures of climate, work environment characteristics, and satisfaction. A comparison of correlations at the individual level, cross-level, cross-level split, aggregate level, and aggregate-split level of analysis revealed that response bias was present across multiple levels. Results suggest that samples should be split in half when cross-level and aggregate correlations are computed to ameliorate response bias problems that arise from individual-level method variance. In Study 2, results indicated that the temporal spacing of measures of climate and satisfaction influenced response bias. Implications and recommendations for future research are discussed.

Observational fear conditioning in the acquisition and extinction of attentional bias for threat: An experimental evaluation.

Anxious persons show automatic and strategic attentional biases for threatening information. Yet, the mechanisms and processes that underlie such biases remain unclear. The central aim of the present study was to elucidate the relation between observational threat learning and the acquisition and extinction of biased threat processing by integrating emotional Stroop color naming tasks within an observational differential fear conditioning procedure. Forty-three healthy female participants underwent several consecutive observational fear conditioning phases. During acquisition, participants watched a confederate displaying mock panic attacks (UCS) paired with a verbal stimulus (CS+), but not with a second nonreinforced verbal stimulus (CS-). As expected, participants showed greater magnitude electrodermal and verbal-evaluative (e.g., distress, fear) conditioned responses to the CS+ over the CS- word. Participants also demonstrated slower color-naming latencies to CS+ compared to the CS- word following acquisition and showed attenuation of this preferential processing bias for threat following extinction. Findings are discussed broadly in the context of the interplay between fear learning and processing biases for threat as observed in persons suffering from anxiety disorders.

Logic and human reasoning: An assessment of the deduction paradigm.

The study of deductive reasoning has been a major paradigm in psychology for approximately the past 40 years. Research has shown that people make many logical errors on such tasks and are strongly influenced by problem content and context. It is argued that this paradigm was developed in a context of logicist thinking that is now outmoded. Few reasoning researchers still believe that logic is an appropriate normative system for most human reasoning, let alone a model for describing the process of human reasoning, and many use the paradigm principally to study pragmatic and probabilistic processes. It is suggested that the methods used for studying reasoning be reviewed, especially the instructional context, which necessarily defines pragmatic influences as biases.
