Capturing the DSM‐5 Alternative Personality Disorder Model Traits in the Five‐Factor Model's Nomological Net

Several studies have shown structural and statistical similarities between the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM‐5) alternative personality disorder model and the Five‐Factor Model (FFM). However, no study to date has evaluated the nomological network similarities between the two models. The relations of the Revised NEO Personality Inventory (NEO PI‐R) and the Personality Inventory for DSM‐5 (PID‐5) with relevant criterion variables were examined in a sample of 336 undergraduate students (M_age = 19.4; 59.8% female). The resulting profiles for each instrument were statistically compared for similarity. Four of the five domains of the two models have highly similar nomological networks, with the exception being FFM Openness to Experience and PID‐5 Psychoticism. Further probing of that pair suggested that the NEO PI‐R domain scores obscured meaningful similarity between PID‐5 Psychoticism and specific aspects and lower‐order facets of Openness. The results support the notion that the DSM‐5 alternative personality disorder model trait domains represent variants of the FFM domains. Similarities of Openness and Psychoticism domains were supported when the lower‐order aspects and facets of Openness domain were considered. The findings support the view that the DSM‐5 trait model represents an instantiation of the FFM.     

Characteristic sounds make you look at target objects more quickly

When you are looking for an object, does hearing its characteristic sound make you find it more quickly? Our recent results supported this possibility by demonstrating that when a cat target, for example, was presented among other objects, a simultaneously presented “meow” sound (containing no spatial information) reduced the manual response time for visual localization of the target. To extend these results, we determined how rapidly an object-specific auditory signal can facilitate target detection in visual search. On each trial, participants fixated a specified target object as quickly as possible. The target’s characteristic sound speeded the saccadic search time within 215–220 msec and also guided the initial saccade toward the target, compared with presentation of a distractor’s sound or with no sound. These results suggest that object-based auditory—visual interactions rapidly increase the target object’s salience in visual search.     

Auditory temporal cues can modulate visual representational momentum

In representational momentum (RM), the final position of a moving target is mislocalized in the direction of motion. Here, the effect of a concurrent sound on visual RM was demonstrated. A visual stimulus moved horizontally and disappeared at unpredictable positions. A complex tone without any motion cues was presented continuously from the beginning of the visual motion. As compared with a silent condition, the RM magnitude increased when the sound lasted longer than and decreased when it did not last as long as the visual motion. However, the RM was unchanged when a brief complex tone was presented before or after the target disappeared (Experiment 2) or when the onset of the long-lasting sound was not synchronized with that of the visual motion (Experiments 3 and 4). These findings suggest that visual motion representation can be modulated by a sound if the visual motion information is firmly associated with the auditory information.     

Characteristic sounds facilitate visual search

In a natural environment, objects that we look for often make characteristic sounds. A hiding cat may meow, or the keys in the cluttered drawer may jingle when moved. Using a visual search paradigm, we demonstrated that characteristic sounds facilitated visual localization of objects, even when the sounds carried no location information. For example, finding a cat was faster when participants heard a meow sound. In contrast, sounds had no effect when participants searched for names rather than pictures of objects. For example, hearing “meow” did not facilitate localization of the word cat. These results suggest that characteristic sounds cross-modally enhance visual (rather than conceptual) processing of the corresponding objects. Our behavioral demonstration of object-based cross-modal enhancement complements the extensive literature on space-based cross-modal interactions. When looking for your keys next time, you might want to play jingling sounds.     

Discrete cortical regions associated with the musical beauty of major and minor chords

Previous research has demonstrated that the degree of aesthetic pleasure a person experiences correlates with the activation of reward functions in the brain. However, it is unclear whether different affective qualities and the perceptions of beauty that they evoke correspond to specific areas of brain activation. Major and minor musical keys induce two types of affective qualities--bright/happy and dark/sad--that both evoke aesthetic pleasure. In the present study, we used positron emission tomography to demonstrate that the two musical keys (major and minor) activate distinct brain areas. Minor consonant chords perceived as beautiful strongly activated the right striatum, which has been assumed to play an important role in reward and emotion processing, whereas major consonant chords perceived as beautiful induced significant activity in the left middle temporal gyrus, which is believed to be related to coherent and orderly information processing. These results suggest that major and minor keys, both of which are perceived as beautiful, are processed differently in the brain.     

Relating momentary affect to the five factor model of personality: A Japanese case1

Abstract: This article shows that fundamental aspects of the structure of momentary affect are similar in Japanese and Canadian societies. We developed questionnaire scales in Japanese in four different formats for assessing self-reported momentary affect. Scales can be scored for dimensions defined by Feldman Barrett and Russell (1998 ), Thayer (1996 ), Larsen and Diener (1992 ), and Watson and Tellegen (1985 ). We administered these newly developed affect scales and NEO five-factor inventory ( Costa & McCrae, 1992 ) to a sample of 450 Japanese respondents. The affect scales were found to be psychometrically sound and to be interrelated, as found with English-speaking Canadians. Dimensions could be integrated into a two-dimensional affective space. Personality correlated with momentary affect, though not in the same pattern as found in Canada.     

Choice Between Two Discrimination Tasks in Chimpanzees (Pan troglodytes)

The purpose of the present study was to investigate the effects of cognitive effort on a chimpanzee's choice between discrimination tasks. The tasks were of the matching-to-sample type. In Experiment 1, the chimpanzee was required to choose between a task providing a high reinforcement rate with high cognitive effort and a task providing a low reinforcement rate with low cognitive effort. Her choice depended on the reinforcement rate more than the cognitive effort. Experiments 2, 3, and 4 examined whether the kind of cognitive effort influenced the chimpanzee's choice. Experiment 2 manipulated the sample-choice relationship, so-called symmetry in the matching-to-sample tasks. Experiment 3 manipulated the number of comparison stimuli. Experiment 4 manipulated the delay interval between the sample and the comparison stimuli. In Experiments 2 and 3, the effects of the cognitive effort were confounded with those of the reinforcement rates. However, in one condition of Experiment 4, the chimpanzee preferred the simultaneous task to the delayed task, despite the lack of a significant difference in reinforcement rates between the two tasks. The present study demonstrated that the chimpanzee's choice of discrimination task depended on the cognitive effort involved, in addition to the reinforcement rate.     

Reactivation-dependent changes in memory states in the terrestrial slug Limax flavus

The change in memory state in the terrestrial slug Limax flavus was studied using cooling-induced retrograde amnesia. Slugs were first conditioned to avoid carrot odor and then a second conditioning procedure was applied 1, 3, 6, or 7 days after the first conditioning trial. Cooling the slugs to approximately 1 degrees C on day 7 immediately after the presentation of the odor used in the conditioning resulted in retrograde amnesia in the slugs that were subject to a second conditioning on day 6 or 7, but not in slugs that were subject to a second conditioning on day 1 or 3. Next, second-order conditioning was used as the second conditioning procedure to distinguish the memory acquired in the first conditioning from that acquired in the second conditioning and similar results were obtained. These results suggest that the reactivation of memory altered the memory state from a cooling-insensitive state to a cooling-sensitive one. A possible model for memory states is discussed.     

Suicide prevention in the Pacific War (WW II).

During the war against Japan, there were two facets of an American program to prevent suicide among the Japanese. One was a research component in the Foreign Morale Analysis Division (FMAD), a subunit of the Office of War Information. The principal FMAD figure who did most of the research on Japanese suicide and ways to prevent suicide among the Japanese military was the anthropologist Ruth Benedict, assisted by her Japanese-American aide Robert Hashima. The second facet was the suicide prevention program itself, which was put into effect toward the end of the war in the battles of Saipan and Okinawa. This program of action was undertaken by American GIs. These unheralded activities in suicide prevention merit a place in the annals of suicide prevention programs.     

On the locus of redundancy effects in a letter-detection task

It takes longer to detect a target if it is the initial letter of a nonredundant letter string such as BNHTW than if it is the initial letter of a redundant letter string such as BBBBB (Johnson, 1986b; Johnson & Blum, 1988). The results of the present study reveal that the redundancy effect also occurs for mixed-case letters strings (e.g., BbbBb) and digit strings (e.g., 22222). In addition, these results suggest that the cause of the redundancy effect is not related to the visual properties of the noninitial letters per se but is instead related to the presence of the target in noninitial positions. Together, these results rule out a number of hypotheses about the cause of the redundancy effect and suggest that the locus of this effect is in processes involved in response selection and/or the read-out of information from the perceptual system.
