Failure to Replicate the Increased Temporal Resolution Induced by Images That Give Impression of Danger

Kobayashi and Ichikawa (2016) recently reported that briefly presented images with dangerous impressions were detected with higher accuracy than images with safe impressions and concluded that the emotion evoked by such images improves temporal resolution of visual perception. In this study, we assessed confounding effects of the color saturations of the images used in their study. While attempting to replicate their results, we found the opposite results—that is, images with safe impressions were detected with higher accuracy than those with dangerous impressions. This likely reflected an observed correlation between color saturations and detection thresholds. To confirm the effects of color saturations, in subsequent experiments, we independently examined the effects of emotion and of color characteristics. We concluded that the previously reported increased temporal resolution was due to the confounding effect of color saturation, and not by the evoked emotion.     

Interaction between creation and appreciation: How linguistic art creation impacts the aesthetic evaluation of haiku poetry and ink paintings

In the psychology of aesthetics, compared with appreciation, there are fewer studies on art creation. This study aims to examine the influence of art creation on appreciation using haiku poetry with reference to the Mirror Model—a process model combining creation and appreciation. Although the model has been primarily used to examine visual arts, we examine its applicability to linguistic arts. In addition, we use ink painting to examine whether a generalisation across artistic genres can occur. The 115 participants were divided into two conditions—creation and control. The former created haiku before and after appreciation, while the latter did not create any haiku. The results showed no improvement in evaluation through creation. Additionally, recognising the difficulty related to creation leads to aesthetic evaluation, and this relationship is mediated by awe. These results expand the existing information regarding the Mirror Model in terms of the different art genres.     

Empathy with fictional stories: reconsideration of the fantasy scale of the interpersonal reactivity index

The present research compared empathy for real people with empathy for fictional characters. 95 university students (53 men, 42 women) ages 18-22 years (M = 19.5, SD = 1.9) completed the Interpersonal Reactivity Index (IRI) and the Fictional IRI. The IRI is a widely used measure of human empathy, and the Fictional IRI contains items from the original IRI that have been modified to investigate empathy for fictional characters. Empathy for characters in fictional stories was found to correlate statistically significantly with empathy for real people on all but a few factors. The results of the present study indicate that empathy for real people and empathy for fictional characters are similar, suggesting that the Fantasy subscale of the IRI, which is limited to fictional stories, should be reconsidered.     

Eidetic-like imagery in hypnosis: rare but there

The production of eidetic-like imagery during hypnosis in subjects with high but not low hypnotizability was supported in three separate experiments using nonfakable stereograms (Julesz, 1971; Gummerman, Gray, & Wilson, 1972). In Experiment 1, 6 (25%) of 24 stringently chosen, high hypnotizables were able to perceive one of the superimposed stereograms (presented monocularly) during conditions of standard hypnosis or hypnotic age regression, or under both conditions, but not during waking. In Experiments 2 and 3, low and high hypnotizables were presented stereograms in an alternating, monocular fashion (one-half to each eye). In Experiment 2, 10% of the high hypnotizables perceived one or more stereograms in hypnosis or age regression, but not during waking. In Experiment 3, none of the 17 low hypnotizables reported correct stereograms, but 6 of the 23 high hypnotizables (26%) did. Relationships between imagery performance and visuo-spatial abilities were investigated. Results support the general hypothesis that hypnosis enhances imaginal processing of information to be remembered that is a literal or untransformed representation.     

Prenatal, perinatal, and early childhood risk factors and drug involvement in adolescence

This study examined prenatal, perinatal, and early childhood risk factors in relation to the etiology of adolescent involvement in cigarettes, alcohol, marijuana, and other illicit drugs. Over a span of 10 years, data were collected on 638 mainly White mother-child pairs at three points in time: at T1, when the children were 1 to 10 years old; at T2, when they were 9 to 18, and again at T3, when they were 11 to 20. Results showed that the early risks of an unwanted pregnancy and major illness were linked to all of the drug categories except "other illicit drugs." Aspects of mutual attachment in the mother-adolescent relationship were negatively correlated with adolescent drug use. Data on the interrelationship of the domains (i.e., sets of variables) of early risk factors and mother-adolescent relations supported an independent model with respect to cigarette and marijuana involvement, a finding in keeping with results showing that early risk did not significantly affect mother-adolescent relations. However, mother-adolescent protective factors were able to mitigate the impact of early risk factors on adolescent drug involvement.     

A network of influences on adolescent drug involvement: neighborhood, school, peer, and family

The interrelationship of neighborhood, school, peer, and family factors and adolescent drug involvement was investigated. Data were collected separately from 518 adolescents and their mothers when the children were between 9 and 18 years of age and again two years later. Neighborhood and school effects were not directly related to adolescent drug use. Neighborhood effects were mediated through the domains of school, peer, and family; school effects were mediated through the peer domain. Family and peer variables had a direct impact on adolescent drug involvement. Risk factors in the adolescents' peer environment can be ameliorated by protective factors in their school environment. Implications for the prevention of drug use are discussed.     

Bounded stability of the quiet standing posture: an intermittent control model

The paper presents a control model of body sway in quiet standing, which aims at achieving bounded stability by means of an intermittent control mechanism. Control bursts are generated when the current state vector exits an area of uncertainty around the reference point in the phase plane. This area is determined by the limited resolution of proprioceptive signals and the burst generation mechanism is predictive in the sense that it incorporates a rough, but working knowledge (internal model) of the biomechanics of the human inverted pendulum. We show that such a model, in spite of its simplicity and of the fact that it relies on very noisy measurements, is robust and can explain in a detailed way the measured sway patterns.     

An ERP study on self-relevant object recognition

We performed an event-related potential study to investigate the self-relevance effect in object recognition. Three stimulus categories were prepared: SELF (participant's own objects), FAMILIAR (disposable and public objects, defined as objects with less-self-relevant familiarity), and UNFAMILIAR (others' objects). The participants' task was to watch the stimuli passively. Results showed that left-lateralized N250 activity differentiated SELF and FAMILIAR from UNFAMILIAR, but SELF and FAMILIAR were not differentiated. In the later time-course, SELF was dissociated from FAMILIAR, indicating the self-relevance effect in object recognition at this stage. This activity did not show consistent lateralization, in contrast to previous studies reporting right lateralization in self-relevant face and name recognition. We concluded that in object recognition, self-relevance was processed by higher-order cognitive functions later than 300ms after stimulus onset.     

Interaction of prime and target in the subliminal affective priming effect

It has been found that an emotional stimulus such as a facial expression presented subliminally can affect subsequent information processing and behavior, usually by shifting evaluation of a subsequent stimulus to a valence congruent with the previous stimulus. This phenomenon is called subliminal affective priming. The present study was conducted to replicate and expand previous findings by investigating interaction of primes and targets in the affective priming effect. Two conditions were used. Prime (subliminal presentation 35 msec.) of an angry face of a woman and a No Prime control condition. Just after presentation of the prime, an ambiguous angry face or an emotionally neutral face was presented above the threshold of awareness (500 msec.). 12 female undergraduate women judged categories of facial expressions (Anger, Neutral, or Happiness) for the target faces. Analysis indicated that the Anger primes significantly facilitated judgment of anger for the ambiguous angry faces; however, the priming effect of the Anger primes was not observed for neutral faces. Consequently, the present finding suggested that a subliminal affective priming effect should be more prominent when affective valence of primes and targets is congruent.
