Repetition priming effects from attended vs. ignored single words in a semantic categorization task

The present research examines priming effects from a centrally presented single-prime word to which participants were instructed to either attend or ignore. The prime word was followed by a single central target word to which participants made a semantic categorization (animate vs. inanimate) task. The main variables manipulated across experiments were attentional instructions (attend vs. ignore the prime word), presentation duration of the prime word (20, 50, 80 or 100 ms), prime-target stimulus onset asynchrony (SOA; 300 vs. 800 ms), and temporal presentation of instructions (before vs. after the prime word). The results showed (a) a consistent interaction between attentional instructions and repetition priming and (b) a qualitatively different ignored priming pattern as a function of prime duration: reduced positive priming (relative to the attend instruction) for prime exposures of 80 and 100 ms, and reliable negative priming for the shorter prime exposures of 20 and 50 ms. In addition (c), the differential priming pattern for attend and ignore trials was observed at a prime-target SOA of 800 ms (but not at a shorter 300-ms SOA) and only when instructions were presented before the prime word. Methodological and theoretical implications of the present findings for the extant negative priming literature are discussed.     

Influence of prime-target relationship on semantic priming effects from words in a lexical-decision task

The present research examines the influence of prime-target relationship (associative and categorical versus categorical only) on priming effects from attended and ignored parafoveal words. Participants performed a lexical-decision task on a single central target, which was preceded by two parafoveal prime words, one of which (the attended prime) was spatially precued. The results showed reliable positive and negative priming effects from attended and ignored words, respectively. However, this priming pattern was observed only for the "associative and categorical", but not for the "categorical only" relationship condition. These results suggest that the lack of semantic priming effects from words in some prior studies may be attributed to the kind of material used (i.e. weakly-associated word pairs).

Projection, Double Bind, and Demonic Possession: Some Common Elements in Three Theories of Psychosis

A desirable goal in science is to identify points at which theories converge. Three theories of psychosis are addressed with respect to three elements they share. The theories are (1) projection, (2) double bind, and (3) demonic possession. The points of convergence are (1) negative injunction, (2) persecutory belief, and (3) obedience to a transcendental command. Implications of the linkage between the elements and theories are drawn.     

Schreber, Perceval, and Van Gogh: Three Eminent Cases Considered from the Perspective of Four Characteristics of Psychosis

The psychotic dispositions of Schreber, Perceval, and Van Gogh are considered. Four characteristics appear to run through their psychoses, and these are identified and illustrated: (1) Negation, (2) persecutory belief, (3) obedience to a transcendental command, and (4) evangelism/martyrdom. Three of the elements have been identified previously, but evangelism/martyrdom is identified here for the first time. The characteristics tend to move in a linear direction, each reinforcing the psychotic state. Therapy requires a disruption of the path, whether through biochemical or psychosocial means or both.     

The Body's Response to Processing Emotional Trauma: Linking Verbal Text with Autonomic Activity

ABSTRACT When individuals talk or think about upsetting experiences, different coping and defensive processes are invoked from one minute to the next. Further, some coping strategies are thought to be more effortful and to be associated with greater biological activity than others. The present research sought to identify how the expression of emotions and the use of different psychological defenses were reflected in momentary changes in autonomic nervous system activity while subjects wrote about emotional topics. A new methodology is introduced that links the production of natural written language with autonomic activity on a word-by-word or phrase-by-phrase basis. Using this technique with a sample of 24 subjects who wrote about traumatic experiences, it was found that certain text dimensions are highly related to skin conductance level (SCL) but not heart rate. In general, subjects' SCLs increased when expressing negative emotions and when using denial and the passive voice. SCLs were more likely to drop when subjects used positive emotion words and self-references and at the conclusion of sentences or thought units. Implications for this methodology for understanding psychological defense and physical health are discussed.     

: Applicants' experiences with discrimination explain their reactions to algorithms in personnel selection

Algorithms might prevent prejudices and increase objectivity in personnel selection decisions, but they have also been accused of being biased. We question whether algorithm-based decision-making or providing justifying information about the decision-maker (here: to prevent biases and prejudices and to make more objective decisions) helps organizations to attract a diverse workforce. In two experimental studies in which participants go through a digital interview, we find support for the overall negative effects of algorithms on fairness perceptions and organizational attractiveness. However, applicants with discrimination experiences tend to view algorithm-based decisions more positively than applicants without such experiences. We do not find evidence that providing justifying information affects applicants—regardless of whether they have experienced discrimination or not.     

Temperament and behaviour problems in children: A multilevel analysis of cross-cultural differences

Early temperament attributes have been linked to emerging behaviour problems and significant long-term consequences; however, these relations are rarely examined cross-culturally. The present study addresses this gap, employing multilevel modelling to explain within- and between-culture variances with respect to temperament predicting a spectrum of behaviour problems across 14 nations from the Joint Effort Toddler Temperament Consortium (JETTC). A total of 865 children between 17 and 40 months, with approximately equal age distribution across this developmental period and about equivalent representation of genders, were recruited from 14 nations. Greater negative emotionality was associated with more internalizing problems, whereas higher surgency and effortful control predicted fewer internalizing difficulties. Controlling for age and gender, temperament explained significant within- and between-culture variances in internalizing and externalizing problems (at the broad-band and fine-grained levels), as well as sleep problems. For internalizing difficulties, temperament accounted for more between-culture variance. In contrast, for externalizing difficulties, temperament accounted more for how individuals within the same culture differed from their same-culture counterparts. The within-culture findings suggest universal patterns of temperament-problem relations, informing cultural adaptation of interventions; between-culture findings enhance understanding of the implications of the cultural niche for normative behaviour and adjustment.
