Multitrait Multimethod validation of Implicit Association Test as a measure of individual differences in personality: Is there personality at all?

The objective of the study was to investigate the validity of IAT in the assessment of the Big five personality traits. We employed the Multi-Trait Multi-Method (MTMM) approach on a sample of 146 respondents. We collected measures on IATs assessing Big five personality traits, self-reports, and two ratings of close others of different gender on NEO PI-R. Additionally, we assessed behavior related to the Big five personality traits in a structured interview where three experts independently provided rating measures. MTMM analyses suggest that personality IAT measures have little in common with personality traits measured traditionally using explicit methods. The evidence does not support the claim that personality IAT can serve as a valid measure of individual differences in personality traits.     

Is the learn unit a fundamental measure of pedagogy?

We propose a measure of teaching, the learn unit, that explicitly describes the interaction between teachers and their students. The theoretical, educational research, and applied behavior analysis literatures all converge on the learn unit as a fundamental measure of teaching. The theoretical literature proposes the construct of the interlocking operant and embraces verbal behavior, social interaction, and translations of psychological constructs into complex theoretical respondent-operant interactions and behavior-behavior relations. Research findings in education and applied behavior analysis on engaged academic time, opportunity to respond, active student responding, teacher-student responding, student-teacher responding, tutor-tutee responding, tutee-tutor responding, and verbal episodes between individuals all support a measure of interlocking responses. More recently, research analyzing the components of both the students' and teachers' behavior suggests that the learn unit is the strongest predictor of effective teaching. Finally, we propose applications of the learn unit to other issues in pedagogy not yet researched and the relation of learn units to the verbal behavior of students.     

Who emerges as a leader? Meta-analyses of individual differences as predictors of leadership emergence

For more than sixty years, the leaderless group discussion (LGD) has been commonly used to assess leadership emergence and potential. This research focuses on individual differences as predictors of leader emergence in LGDs. Meta-analytic methods allowed us to combine and compare results from 45 studies, producing 196 effect sizes, and make statistically guided decisions about the strength of relationships between individual difference and personality variables and leadership emergence in LGDs. Consistent with more general research on leader emergence and effectiveness, we found a number of individual differences predictive of leader emergence in LGDs, most notably extraversion and authoritarian personality. This research augments previous meta-analytic research on personality and leadership with a focus specifically on the leaderless group discussion.     

Is the area measure a historical anomaly?

Green's well-known area theorem establishes an equivalence between the area under the yes-no ROC curve and the percent correct of an unbiased observer in a two-alternative forced-choice (2AFC) task with equivalent stimuli. In this article, we show that this conversion from yes-no detection data to hypothetical performance in a 2AFC task is unnecessary: The same yes-no detection data that are used to compute the area statistic can always be used to compute the percent correct of an unbiased observer in the yes-no detection task itself. We also show that the ROC curve may not be the ideal graphical device for many investigators. A more natural representation of the difficulty of a discrimination task is obtained by plotting the distribution of the posterior betting odds under equal base rates, which can be estimated from their distributions under unequal base rates. Finally, unlike the area measure and other traditional detection theory statistics, both the yes-no percent correct measure and the odds distributions generalize in an obvious and direct way to classification paradigms with more than two responses (e.g., identification).     

Is the fluency of language outputs related to individual differences in intelligence and executive function?

There has been little research on the fluency of language production and individual difference variables, such as intelligence and executive function. In this study, we report data from 106 participants who completed a battery of standardized cognitive tasks and a sentence production task. For the sentence production task, participants were presented with two objects and a verb and their task was to formulate a sentence. Four types of disfluency were examined: filled pauses (e.g. uh, um), unfilled pauses, repetitions, and repairs. Repetitions occur when the speaker suspends articulation and then repeats the previous word/phrase, and repairs occur when the speaker suspends articulation and then starts over with a different word/phrase. Hierarchical structural equation modeling revealed a significant relationship between repair disfluencies and inhibition. Conclusions focus on the role of individual differences in cognitive ability and their role in models and theories of language production.     

Is flanker-based inhibition related to age? Identifying specific influences of individual differences on neurocognitive variables

Researchers frequently attempt to identify the specific neurocognitive processes that might be responsible for differences in performance associated with neurological status or other individual difference characteristics by administering two or more conditions of an experimental task to different groups of participants, and focusing on the group-by-condition interaction as the primary outcome of interest. Three limitations of this approach are discussed, and an alternative analytical method is proposed to overcome the limitations. The method is demonstrated in analyses of data from 10 cognitive tasks in two independent studies, including two flanker tasks which are often used to assess aspects of inhibition.     

Do individual differences in intolerance of uncertainty affect health monitoring?

Researchers have postulated that individual differences in intolerance of uncertainty (IU) may affect people's health behaviours. Study 1 (N?=?147 university students) supports this proposition showing that higher IU is associated with higher monitoring (seeking threat-relevant information). Study 2 (N?=?117 university students) experimentally manipulated IU to ensure that the association is not due to other related constructs such as anxiety or worry. Results show that inducing high IU led to increased monitoring as reflected by higher scores on an index of monitoring measures. Wanting information about the health threat in order to reduce their uncertainty was an independent predictor of monitoring and did not mediate the relationship between IU and monitoring. Findings suggest that high IU induces people to increase their monitoring; an adaptive strategy when the health threat can be reduced through this behaviour.     

The “idealized individual” interpretation of individual differences in multidimensional scaling

It is shown that several variants of the Tucker-Messick points of view procedure are interpretable in terms of their idealized individual concepts. It is contended that the main function of the method is that it allows the computation ofseveral vectors of mean judgments instead of only one and that each of these may be used to stand for the actual judgments of a subgroup of subjects. Vectors that do not correspond to the judgments of any subjects are to be avoided. It is alleged that Ross's interpretation of points of view is quite different from that intended by Tucker and Messick.The preparation of this paper was supported in part by Contract Nonr-228(32) between the Office of Navel Research and the University of Southern California.     

Is there a place for individual subjectivity within a social constructionist epistemology?

The epistemological turn towards social constructionism has become well established within the field of family systemic therapy. Social constructionism has provided therapists with a theoretical rationale for the concentration upon the social context within which individuals and families live their lives. This is a philosophical position that pushes to the margins the positivist premise that individuals have fixed and measurable personalities in favour of a discourse which proposes that the person is encountered differently within different social contexts. Prompted by the growing interest in systemic practice with individuals and by the rediscovery of the psychoanalytic canon within family therapy literature, the adequacy of this position is examined and an attempt is made to open up a space within social constructionist discourse for a theory of individual subjectivity. Findings from a research project are the starting point for this venture. These findings are understood through the lens of psychoanalytic theory, with particular reference to the work of Jacques Lacan.     

Is one item an adequate measure of cognitive learning?

While the "leaning loss" scale is a valid means of estimating cognitive learning, the test is valid only when used as designed-with two items.     

To translate or to develop a measure? The case of a new Arabic measure of organizational justice

One of the most prominent and widely used self‐reporting scales for assessing organizational justice perceptions was developed by Colquitt (2001). This scale has been used internationally and has therefore been translated into several languages including Arabic. In a recent study, after conducting a careful review of organizational justice literature to ensure its relevance to Arabic culture, Alkhadher and Gadalreb ( 2016 ) developed a new Arabic measure of organizational justice (AMOJ) perceptions and found evidence of a four‐factor scale structure. The purpose of this study is to compare the Arabic version of Colquitt's measure of organizational justice (AVCMOJ) with the AMOJ in terms of predictive power using various outcome measures used by Colquitt (2001). The two scales were administered to 781 Kuwaiti employees (47.6% males) from the public sector. A multiple‐sample confirmatory factor analysis supports the four‐dimensional structure for both AVCMOJ and AMOJ measures. Cronbach's alpha obtained for subscales was found to range between 0.72 and 0.85. The predictive power of the three AMOJ dimensions (distributional, procedural, and informational) was found to be higher than that of the AVCMOJ. The results of the present study raise issues of scale development against the translation of well‐developed scales. Theoretical and practical implications of the results are discussed.     

Do state laws concerning homosexuals reflect the preeminence of conservative-liberal individual differences?

The present study was conducted to determine whether individual-level correlates of sexual prejudice (i.e., conservatism-liberalism, religious fundamentalism, educational levels, urbanism, income, and living in the South) are predictive at the state level of laws restricting homosexual behaviors and desires. Criterion 1 was a multifaceted index of state laws concerning gay men and lesbians; Criterion 2 was an index of state laws regarding same-sex partnerships. Multiple regression strategies showed that state conservatism-liberalism, as determined from the responses of 141,798 individuals aggregated at the state level (Erikson, Wright, & McIver, 1993), was the prime state-level predictor of both criteria. For Criterion 1, only Southern state status accounted for additional variance (4.2%) above the 54.8% already accounted for by conservatism-liberalism. For Criterion 2, no other variables accounted for variance beyond the 44.6% accounted for by state conservatism-liberalism.     

What do Raven's Matrices measure? An analysis in terms of sex differences

Although it is sometimes claimed that Raven's Matrices provide an almost pure measure of g, there is evidence that the easier items in the Standard Progressive Matrices and in Set I of the Advanced Matrices measure a perceptual or Gestalt factor distinct from the more analytic items in the rest of the tests. There is also, however, both factor analytic and experimental evidence that these analytic items fall into two partially separate groups, distinguishable by the type of rule needed for their solution in the analysis proposed by Carpenter, Just, and Schell (1990) [Carpenter, P. A., Just, M. A., Schell, P. (1990). What one intelligence test measures: A theoretical account of the processing in the Raven's Progressive Matrices Test. Psychological Review, 97, 404–431]. Re-analysis of published data suggests a new source of evidence for this further distinction: males do better than females on items requiring an addition/subtraction or distribution of two rule, but there is no sex difference on items requiring pairwise progression or distribution of three rules. A specially designed experiment confirmed this pattern of results.     

Is there a universal positivity bias in attributions? A meta-analytic review of individual, developmental, and cultural differences in the self-serving attributional bias

Researchers have suggested the presence of a self-serving attributional bias, with people making more internal, stable, and global attributions for positive events than for negative events. This study examined the magnitude, ubiquity, and adaptiveness of this bias. The authors conducted a meta-analysis of 266 studies, yielding 503 independent effect sizes. The average d was 0.96, indicating a large bias. The bias was present in nearly all samples. There were significant age differences, with children and older adults displaying the largest biases. Asian samples displayed significantly smaller biases (d = 0.30) than U.S. (d = 1.05) or Western (d = 0.70) samples. Psychopathology was associated with a significantly attenuated bias (d = 0.48) compared with samples without psychopathology (d = 1.28) and community samples (d = 1.08). The bias was smallest for samples with depression (0.21), anxiety (0.46), and attention-deficit/hyperactivity disorder (0.55). Findings confirm that the self-serving attributional bias is pervasive in the general population but demonstrates significant variability across age, culture, and psychopathology.     

Group vs individual equity judgments: Is there a polarization effect?

Two-hundred male undergraduates, individually and in groups of five, divided a fixed reward between two performers with unequal inputs under conditions in which they either expected or did not expect future interaction with recipients. Individuals who anticipated future interaction with recipients divided the reward equally, while groups divided the reward equitably. When interaction was not expected, individuals divided the reward equitably by discriminating between recipients, while groups made more extreme discriminations (the group polarization effect). Experiencing group discussions made individuals more confident in the fairness of their subsequent allocations. The results are discussed in terms of the social and informational influences of groups on allocation decisions.     

Is the matching familiar figures test a measure of cognitive style? A warning for users

A probabilistic model of reflection-impulsivity as measured by the Matching Familiar Figures Test (MFFT) is presented and tested on 77 fourth graders. In testing the model two groups emerged, a random response group (n = 22) and a cognitive response group (n = 55), who use the evaluation process. Correlations among latencies, total errors, initial errors, school-scores, and IQs were compared for our total sample and the two groups. The correlation of MFFT latencies and errors disappeared for the random-response group and new correlations with errors appeared while the cognitive response group kept a statistically significant correlation of latencies with errors and no other error correlation was shown. This last group was classified by Kagan's median-split procedure showing that most reflective subjects kept their classification. Preliminary results suggest a reinterpretation of reflection-impulsivity literature, especially as related to the impulsive style.     

The Psychiatric Impairment Rating Scale: Is it a valid measure?

The Psychiatric Impairment Rating Scale (PIRS) was introduced as part of the Workcover legislation in NSW and has since been adopted in other States. There has been significant criticism of its validity and structure, but no supporting research. This study was undertaken to examine the validity of the use of the PIRS to assess psychiatric impairment. This study assesses the concurrent validity of the PIRS by comparing it with the Comcare and Social Security scales and the Health of the Nation Outcome Scale, together with two self‐report measures. It also examines the relationship between the PIRS subscales. A high level of ordinal concordance was demonstrated between all scales although the ratings obtained had major systematic variations between scales in both level and distribution. The scoring technique in the PIRS transforms normally distributed scores to a skewed distribution with a preponderance of low scores. The PIRS is a valid scale for ordering the severity of psychological disability but it measures disability rather than impairment. The form of scoring does not provide a proportionate or statistically meaningful measure.
