Does Acquisitive Self‐Presentation in Personality Self‐Ratings Enhance Validity? Evidence from two experimental field studies

The aim of the present research was to demonstrate that acquisitive self‐presentation in personality scales is not a barrier to their criterion‐related validities in human resource contexts, but rather a means to improve them. A pilot study (Study 1) with 96 job incumbents provided preliminary positive evidence. In Study 2, in the experimental group (n=99), the instructions asked job incumbents to work on a Big‐Five personality inventory (BFI‐K) as if they took part in a personnel selection procedure for a personally very attractive position. In the control group (n=93) of Study 2, job incumbents were asked to answer the inventory items honestly. As expected, the correlation between the self‐ratings of the motive to get along (i.e., which comprises emotional stability, conscientiousness, and agreeableness) and contextual performance assessments was significantly higher in the experimental group than in the control group in Study 2. Additionally, the correlation between the self‐ratings of the motive to get ahead (i.e., which comprises extraversion and openness to experience) and task performance and leadership assessments was significantly higher in the experimental group than in the control group in Study 2. It is proposed that responding to a personality inventory in a human resource decision situation should be conceptualized as a workplace simulation.     

Recognition of affective prosody in brain-damaged patients and healthy controls: A neurophysiological study using EEG and whole-head MEG

A passive oddball experiment was used in which stimuli were emotional exclamations differing in their affective tone. In both electroencephalography (EEG) and magnetoencephalography (MEG), deviants elicited an N300 component, sometimes accompanied by a slow wave. Both components had a symmetrical distribution, but the former was more posterior than the latter. The same responses to prosodic stimuli were significant in 6 of 27 patients with severe disorders of consciousness (persistent vegetative state and minimally conscious state) and in all 3 of the examined locked-in patients, indicating that the procedure can be applied for testing neurological patients. The occurrence of significant responses depended on the presence or absence of a lesion to the right temporal lobe. Obviously, the N300 depends on the activity of the right temporal cortex but does not originate there. We suggest that the component is related not to the recognition of affective prosody as such, but to the following detection of affective mismatch due to violations of emotional context of stimulation.     

Preview benefit and parafoveal-on-foveal effects from word n + 2

Using the gaze-contingent boundary paradigm with the boundary placed after word n, the experiment manipulated preview of word n + 2 for fixations on word n. There was no preview benefit for 1st-pass reading on word n + 2, replicating the results of K. Rayner, B. J. Juhasz, and S. J. Brown (2007), but there was a preview benefit on the 3-letter word n + 1, that is, after the boundary but before word n + 2. Additionally, both word n + 1 and word n + 2 exhibited parafoveal-on-foveal effects on word n. Thus, during a fixation on word n and given a short word n + 1, some information is extracted from word n + 2, supporting the hypothesis of distributed processing in the perceptual span.     

Who visits online dating sites? Exploring some characteristics of online daters.

Although online dating has become an important strategy in finding a romantic partner, academic research into the antecedents of online dating is still scarce. The aim of this study was to investigate (a) the demographic predictors of online dating and (b) the validity of two opposite hypotheses that explain users' tendency to use the Internet for online dating: the social compensation and the rich-get-richer hypotheses. We presented 367 single Dutch Internet users between 18 and 60 years old with an online questionnaire. We found that online dating was unrelated to income and educational level. Respondents between 30 and 50 years old were the most active online daters. In support of the rich-get-richer hypothesis, people low in dating anxiety were more active online daters than people high in dating anxiety.     

New methods in ambulatory blood pressure monitoring: Interactive monitoring and detection of posture and movement patterns

Psychophysiological monitoring can be used to assess emotional reactivity in cardiovascular measures. Since blood pressure (BP) variability in daily life is primarily caused by physical activity, metabolic and nonmetabolic effects are confounded. A newly developed method of multiple accelerometry allows for the control of such unwanted variances by continuously detecting posture, general activity, and distinct movement patterns. Contingent on episodes of additional heart rate (AHR), an indicator of emotional reactivity, BP measurements can be triggered and participants prompted to enter their current mood in a handheld PC. To evaluate both new methods for BP research, we performed 24-h ambulatory monitoring with 40 normotensive student participants, an evaluation designed to include standard settings for a controlled comparison (library vs. cinema). Findings indicated that the group at the cinema showed higher values of AHR, but group differences in BP were not observed. On the whole, such multiple accelerometry and interactive monitoring appear to be useful methods in behavior research.     

Perception of danger signals: the role of control

How does the perceptual system process stimuli that signal aversive outcomes or dangers? Considering the functional links between perception, attention, and action regulation, we posit that when people can avoid the aversive consequences, sensitivity of the perceptual system to danger signals should be enhanced, whereas it should be reduced when there is no such option. To test this prediction, we used a search task in which tachistoscopically presented conjunctions of features had to be detected. Parameters of sensitivity and response bias were analyzed drawing on procedures from signal detection theory. Although the experimental procedure rewarded correct responses, the predicted asymmetry emerged. For stimuli that were linked to a negative consequence (loss of points in the experimental game), perceptual sensitivity was enhanced when participants had the opportunity to neutralize the loss in a second task; an opposite pattern emerged when they had no such opportunity.     

The positivity proportion effect: A list context effect in masked affective priming

In the evaluative decision task, participants decide whether target words denote something positive or negative. Positive and negative prime words are known to engender so-called affective priming effects in this task. Primes were sandwich masked, and the proportion of positive to negative target words was manipulated. In Experiment 1, prime valence and positivity proportion interacted, so that primes of the less frequently presented target valence caused larger priming effects. Experiment 2 rendered an explanation of this interaction in terms of response bias unlikely, Experiment 3 ruled out a peripheral locus of the effect, and Experiment 4 ruled out an account in terms of stimulus repetition. The effect is explained by means of an attentional bias favoring the rare kind of valence.     

Treatment rejecting and treatment seeking personality disorders: Type R and Type S

An important distinguishing feature of one group of personality disorders is the wish of the sufferer to seek treatment. For another group this wish is rarely entertained. Although there is some variation between different types of personality disorder the wish to change is not confined to any one diagnostic category. A useful subclassification of personality disorders is therefore into Type R (treatment rejecting) and Type S (treatment seeking) personality disorders, and these are defined operationally. The classification of 68 personality disordered patients on the caseload of an assertive community team using a simple scale showed a 3 to 1 ratio between Type R and Type S personality disorders with Cluster C personality disorders being significantly more likely to be Type S, and paranoid and schizoid (Cluster A) personality disorders significantly more likely to be Type R than others. It is suggested that this typology is useful for those contemplating treatment with those who have personality disorders.     

Action-feature integration blinds to feature-overlapping perceptual events: evidence from manual and vocal actions

Previous studies showed that the identification of a left- or right-pointing arrowhead is impaired when it appears while planning and executing a spatially compatible left or right keypress (Müsseler & Hommel, 1997a). We attribute this effect to stimulus processing and action control operating on the same feature codes so that, once a code is integrated in an action plan, it is less available for perceptual processing. In three pairs of experiments we tested the generality of this account by using stimulus-response combinations other than arrows and manual keypresses. Planning manual left-right keypressing actions impaired the identification of spatially corresponding arrows but not of words with congruent meaning. On the contrary, planning to say "left" or "right" impaired the identification of corresponding spatial words but not of congruent arrows. Thus, as the feature-integration approach suggests, stimulus identification is impaired only with overlap of perceptual or perceptually derived stimulus and response features while mere semantic congruence is insufficient.
