Anchoring and Adjusting in Questionnaire Responses

Do survey designers bias respondents' answers on attitude/opinion questionnaires through the organization of their survey items? We hypothesize that respondents often employ an anchoring and adjusting strategy in which their response to an initial survey item provides a cognitive anchor from which they insufficiently adjust in answering the subsequent item. Three experiments indicate that respondents often anchor and insufficiently adjust in certain situations. Ultimately, this tendency can affect reliability estimates of scales and the resultant correlations with other measures. In organizing their surveys, researchers may wish to combat this bias by intermixing items designed for different but related constructs.     

Interracial Couples: Situational Factors in White Male Reactions

Two problems in the measurement of prejudice are the theoretical orientation underlying its measurement and the sensitivity of prejudice measures to social desirability. Most previous studies of prejudice have either not attempted to use sexual threat as a measurement model or have been plagued by other measurement problems. By introducing an unobtrusive procedure that overcomes those measurement problems, this study has tested a sexual-threat model as well as an incentive-conflict model. It was found that sexual threat does affect responses to interracial couples but that those responses are also affected by the value support that interracial couples provide for white norms, as predicted by incentive conflict.     

Facing being: the significance of Thomist ontological epistemology to realism in post-Kantian philosophy

The Kantian ‘Copernican Revolution’ contained in his Prologomena and The Critique of Pure Reason deemed metaphysical statements to be ‘transcendental illusions’, so directing metaphysics to its dearth. As a consequence, no longer could objects be known ‘in-themselves’ by the sensorily-reliant human. This perceived impossibility of metaphysical knowledge in the turn to the subject from Kant through Nietzsche's rejection of true knowledge has heavily inclined Continental Philosophy to an anti-metaphysical quandary. Analytic Philosophy is no different following the influence of Carnap, Wittgenstein and Rorty upon its own ‘linguistic turn’. An inevitable consequence of things not being knowable in themselves is the philosophical distance from ‘the world’, which Stephen Hawking has argued, makes the philosophical enterprise ‘dead’. In dialogue with this widespread decline in metaphysics, I will attempt to reclaim realist metaphysics through the employment of a Thomist paradigm. If philosophy is to be relevant to the knowledge economy, it is compelled to be in relation with what is. Thus, in my theoretical framework, being will be considered as central to all knowledge systems seeking to correspond to ‘hard’ science. The Thomist realist natural philosophy of ‘scientia’ – wherein truth is conformed with being – will be at the core of the argument. This paper challenges the ignoring of being because extant reality is composed of all that is, continuously faced and never evadable. Consequently, Thomism is recaptured as significant to post-Kantian philosophy as Aquinas articulated a means through which the thinking subject engages with being through sensation and cognition.     

That's disgusting! …, but very amusing: Mixed feelings of amusement and disgust

This study examines mixed feelings of amusement and disgust. Participants (N=102) reported their affect before and after watching a film clip depicting disgusting humour. While watching the clip participants were instructed to take the perspective of either an uninvolved observer or of the clip's protagonist. As expected this clip produced mixed feelings of amusement and disgust, and perspective moderated changes in affect and mixed feelings. Disgust increased equally in both conditions and amusement increased only in the observer condition. As a result mixed feelings of amusement and disgust were more intense in the observer condition. As the first study to demonstrate moderation of mixed feelings, this work adds to the extant literature on mixed feelings and has implications for emotion research.     

Reduced memory for the spatial and temporal context of unpleasant words

Emotional stimuli are consistently better remembered than neutral stimuli. However, the reported effects of emotional stimuli on source memory are less consistent. In four experiments, we examined spatial and temporal source memory and free recall for emotional words previously studied in an fMRI experiment. In the fMRI experiment, the unpleasant but not the pleasant words were shown to activate the amygdala. In the experiments reported here, spatial and temporal source memory were reduced for the unpleasant words compared to pleasant and neutral words. Reduced spatial memory for unpleasant words was observed across studies that varied the specific stimuli, task conditions, and incidental versus intentional encoding instructions. Free recall was enhanced for the pleasant and unpleasant words compared to neutral words. The results demonstrate reduced source memory for unpleasant words even when item recall is enhanced. Our findings are consistent with prior reports of amygdala-mediated amnestic effects evoked by unpleasant stimuli.     

On the relative effectiveness of affect regulation strategies: A meta-analysis

To examine the effectiveness of various affect regulation strategies and categories of affect regulation strategies, a meta-analysis was conducted. Results generally indicate that reappraisal (d=0.65) and distraction (d=0.46 for all studies; d=0.95 for studies with a negative or no affect induction) are the most effective regulation/repair strategies, producing the largest hedonic shift in affect. The effectiveness of different categories of regulation/repair strategies depended on the valence of the preceding affect induction. Results also indicate that stronger affect inductions and the use of bivariate affect measures will provide a richer understanding of affect regulation. Additionally, not all specific strategies or categories of strategies have been researched and the impact of individual differences on affect regulation has received relatively little attention. Finally, results indicate that control conditions in affect regulation research may not provide a valid point for comparison, as they facilitate effective affect repair.     

Cognitive-emotional dysfunction among noisy minds: Predictions from individual differences in reaction time variability

Mental noise can be defined as less reliable information processing. Individuals with high levels of mental noise are thought to be disadvantaged in cognitive, emotional, and behavioural realms. The present five studies (total N=298) investigated such potential disadvantages among normally functioning college undergraduates. Mental noise was operationalised in terms of the reaction time coefficient of variation (RTCV), a measure of RT variability that corrects for average levels of mental speed. Individuals with higher RTCV exhibited less effective cognitive control (Studies 1 and 5), less controlled behaviour (Study 2), and were more prone to negative emotional experiences (Study 3) and depressive symptoms (Study 4). Study 5 extended these results and found that individuals higher (versus lower) in RTCV were more adversely affected by their attentional lapses in daily life. Results converge on the idea that mental noise is an important individual difference dimension with multiple adverse correlates and consequences.     

Functional versus dysfunctional team change: Problem diagnosis and structural feedback for self-managed teams

We describe and examine three changes (personnel, process, and structure) that self-managed teams can make to remedy performance problems. We also discuss why self-managed teams may over-emphasize process and (to a lesser extent) personnel changes over structural changes. Furthermore, we describe and test two specific diagnostic feedback interventions aimed at helping teams make functional structural change. Seventy-eight 4-person teams of undergraduate students participated in two trials of a networked laboratory simulation task. All teams were initially structurally misaligned and subsequently received (a) no feedback, (b) one type of feedback only, or (c) both types of feedback. Results confirmed that structurally misaligned teams demonstrated dysfunctional change by changing process more frequently than structure, with detrimental effects for subsequent performance. When teams received the feedback interventions, however, they were more likely to change their structure and thereby improve their performance.     

Neuropsychological sequelae following pediatric stroke: A nonlinear model of age at lesion effects

Aim: The distribution and quality of brain recovery following pediatric arterial ischemic stroke remains controversial. The literature suggests that age at stroke may be an important modulator of neuropsychological outcome, with reports inferring either greater vulnerability or plasticity in the nascent brain. Our aim was to investigate neuropsychological outcomes following pediatric stroke in a clinical sample with reference to age at lesion, lesion laterality, elapsed time from stroke to assessment, and persistent neurological sequelae.

Methods: Using comprehensive neuropsychological assessment batteries, we investigated retrospectively a large (n?=?44) and evenly distributed group of children who had ischemic stroke during “infancy” (1 month to 1 year), “early childhood” (1 to 6 years), and “late childhood” (6 to 16 years).

Results: Children who suffered a stroke performed significantly worse on a range of neuropsychological measures when compared to a normative sample. However, children who suffered a stroke between 1 and 6 years old demonstrated better preserved neuropsychological profiles than either the earlier (before age 1) or later (after age 6) age groups. In addition, those children suffering a left hemisphere lesion performed more poorly on a range of neuropsychological measures than did children with right hemisphere lesions.

Interpretation: Age at stroke is an important determinant of recovery following insult and may modulate neuropsychological and cognitive outcome.     

A Comparison of the Cross-Sectional and Sequential Designs when Assessing Longitudinal Mediation

Mediational studies are often of interest in psychology because they explore the underlying relationship between 2 constructs. Previous research has shown that cross-sectional designs are prone to biased estimates of longitudinal mediation parameters. The sequential design has become a popular alternative to the cross-sectional design for assessing mediation. This design is a compromise between the cross-sectional and longitudinal designs because it incorporates time in the model but has only 1 measurement each of X, M, and Y. As such, this design follows the recommendation of the MacArthur group approach, which stresses the importance of multiple waves of data for studying mediation. These 2 designs were compared to see whether the sequential design assesses longitudinal mediation more accurately than the cross-sectional design. Specifically, analytic expressions are derived for the bias of estimated direct and indirect effects as calculated from the sequential design when the actual mediational process follows a longitudinal autoregressive model. It was found that, in general, the sequential design does not assess longitudinal mediation more accurately than the cross-sectional design. As a result, neither design can be depended on to assess longitudinal mediation accurately.
