The use of personality test norms in work settings: Effects of sample size and relevance

The value of personality test norms for use in work settings depends on norm sample size (N) and relevance, yet research on these criteria is scant and corresponding standards are vague. Using basic statistical principles and Hogan Personality Inventory (HPI) data from 5 sales and 4 trucking samples (N range=394–6,200), we show that (a) N>100 has little practical impact on the reliability of norm‐based standard scores (max=±10 percentile points in 99% of samples) and (b) personality profiles vary more from using different norm samples, between as well as within job families. Averaging across scales, T‐scores based on sales versus trucking norms differed by 7.3 points, whereas maximum differences averaged 7.4 and 7.5 points within the sets of sales and trucking norms, respectively, corresponding in each case to approximately ±14 percentile points. Slightly weaker results obtained using nine additional samples from clerical, managerial, and financial job families, and regression analysis applied to the 18 samples revealed demographic effects on four scale means independently of job family. Personality test developers are urged to build norms for more diverse populations, and test users, to develop local norms to promote more meaningful interpretations of personality test scores.     

Parietal control of attentional guidance: the significance of sensory, motivational and motor factors

The lateral intraparietal area (LIP), a portion of monkey posterior parietal cortex, has been implicated in spatial attention. We review recent evidence showing that LIP encodes a priority map of the external environment that specifies the momentary locus of attention and is activated in a variety of behavioral tasks. The priority map in LIP is shaped by task-specific motor, cognitive and motivational variables, the functional significance of which is not entirely understood. We suggest that these modulations represent teaching signals by which the brain learns to identify attentional priority of various stimuli based on the task-specific associations between these stimuli, the required action and expected outcome.     

Symptoms of PTSD Among Adolescents and Young Adult Survivors Six Years after the 2010 Haiti Earthquake

This study investigates the long-term consequences for adolescents and young adults who experienced the January 12, 2010, earthquake that struck Haiti. It aims to evaluate the consequences of the earthquake in adolescents and young adults six years after the disaster. During May and June 2016, in Port-au-Prince, 723 adolescents and young adults (364 girls and young women) aged 14 to 24 were assessed by means the Impact of Event Scale–Revised (IES-R) in addition to social demographic characteristics. In our sample, 35.82% reported clinically significant symptoms of PTSD, with a higher prevalence for girls and young women. They also had consistently higher scores than boys and young men on every subscale. Participants with working parents had consistently higher scores across all the subscales than participants whose parents did not work. This study showed that, more than six years after the earthquake, more than one third of the participants assessed had severe PTSD symptoms. Our results may prove useful for setting up mental health programs and devising tools appropriate for the youth population in Haiti.     

The “Loving Parent” analogy

A crucial part of William Rowe’s evidential argument from evil implies that God, like a loving parent, would ensure that every suffering person would be aware of his comforting presence. Rowe’s use of the “loving parent” analogy however fails to survive scrutiny as it implies that God maximally loves all persons. It is the argument of this paper that no one could maximally love every person; and whatever variation there is in the divine love undercuts the claim that every suffering person would be aware of the divine presence.     

“For They Knew Not What It Was”: Rethinking the Tacit Narrative History of Religion and Health Research

Over the past couple of decades, research on religion and health has grown into a thriving field. Misperceptions about the history and scope of this field, however, continue to exist, especially among new investigators and commentators on this research. Contrary to the tacit narrative, published research and writing date to the nineteenth century, programmatic research to the 1950s, and NIH funding to 1990; elite medical journals have embraced this topic for over 100 years; study populations are religiously and sociodemographically diverse; and published findings are mostly positive, consistent with psychosocial theories of health and confirmed by comprehensive reviews and expert panels.     

Mental Causation is Not Just Downward Causation

According to a popular model of mental causation, an irreducible mental cause M1 brings about an irreducible mental effect M2 by bringing about M2's supervenience base (ground, realizer, etc.), P2. Call this ‘the Downward Causation View’. This paper raises doubts about the Downward Causation View on grounds that M1 does not cause M2 immediately and there is no causal chain from M1 to M2. Prima facie, then, M1 does not cause M2 on this view. But a theory of mental causation ought to account for how some mental phenomena cause other mental phenomena; so rival theories are to be preferred. After setting out the problem, I consider replies; all fail. 1     

The impact of evidence lineups on fingerprint expert decisions

Forensic examiners routinely compare a crime-relevant mark of unknown origin against a single suspect's sample, which may create an expectation that the two will match. We tested how embedding the suspect's sample among known-innocent fillers (i.e., an evidence lineup) affects expert decision-making. Experienced fingerprint examiners (N = 43) compared crime-relevant marks against either individual suspect fingerprints (i.e., the standard procedure) or arrays of fingerprints (i.e., evidence lineups), with a matching fingerprint either present or absent. Evidence lineups promoted conservative decision-making, as evidenced by fewer correct IDs and a higher rate of inconclusive judgments. Though errors were rare, evidence lineups also occasionally revealed errors that would have otherwise gone undetected. Our findings thus support arguments that evidence lineups can expose fraud, identify flawed methodologies, and curb overconfidence. The potential benefits and challenges of implementing evidence lineups in forensic laboratories are discussed.     

Some Aspects of Polyadic Inductive Logic

We give a brief account of some de Finetti style representation theorems for probability functions satisfying Spectrum Exchangeability in Polyadic Inductive Logic, together with applications to Non-splitting, Language Invariance, extensions with Equality and Instantial Relevance.     

Is happiness having what you want, wanting what you have, or both?

Rabbi Hyman Schachtel (1954) proposed that "happiness is not having what you want, but wanting what you have" (p. 37). In two studies, we tested Schachtel's maxim by asking participants whether or not they had and the extent to which they wanted each of 52 material items. To quantify how much people wanted what they had, we identified what they had and the extent to which they wanted those things. To quantify how much people had what they wanted, we identified how much they wanted and whether or not they had each item. Both variables accounted for unique variance in happiness. Moreover, the extent to which people wanted what they had partially mediated effects of gratitude and maximization on happiness, and the extent to which they had what they wanted partially mediated the effect of maximization. Results indicate that happiness is both wanting what you have and having what you want.     

Interpersonal politics: the role of terror management and attachment processes in shaping political preferences

Research on terror management theory (TMT) indicates that reminders of death affect political attitudes, but political orientation only sometimes moderates these effects. We propose that secure relationships are associated with values of tolerance and compassion, thus orienting people toward liberalism; insecure attachments are associated with more rigid and absolutist values that orient people toward conservatism. Given that attachment relationships become especially active when security needs are heightened, we predicted that mortality salience would be an important factor in understanding the relationship between attachment processes and political orientation. Supporting these ideas, Study 1 showed that after a mortality-salience manipulation, securely attached participants increased their support for a liberal presidential candidate, and less securely attached participants increased their support for a conservative presidential candidate. In Study 2, a secure-relationship prime following a mortality-salience manipulation engendered a less violent approach to the problem of terrorism than did a neutral-relationship prime. We discuss the interaction of TMT processes and individual differences in attachment in shaping political preferences.
