Self-structure in schizophrenia

This study used a set-theoretical model to construct self-perception structures and person-perception structures for 10 recently hospitalized schizophrenic patients, 10 nonschizophrenic patients recently hospitalized for depression, and 10 nonpsychiatric subjects. Overall self-perception structures were significantly less elaborated in the schizophrenic patients when compared with either the psychiatric or the nonpsychiatric comparison group. No comparable differences were found for measures taken from the person-perception structures. The degree of elaboration of self in the particular context of self as psychiatric patient was found to be correlated (r = .74, p less than .01) with Global Assessment Scale ratings of current functional level in the schizophrenic group.     

Frequency synthesis with the Commodore Amiga for research on perception and memory of pitch

The potential of the Commodore Amiga as a digital synthesizer for research and demonstration in psychoacoustics and memory is discussed. Economy, ease of use, flexibility, portability, and accuracy outweigh disadvantages of narrow bandwidth, narrow dynamic range, and storage limitations for many applications encountered in pilot research and education. The Amiga also bears serious consideration for psychoacoustic studies requiring frequencies below 4000 Hz and modest signal-to-noise ratio, as exemplified by an implementation for research in absolute judgment, similarity scaling, and sequential pattern tracking.     

Dorsal anterior cingulate and ventromedial prefrontal cortex have inverse roles in both foraging and economic choice

Recent research has highlighted a distinction between sequential foraging choices and traditional economic choices between simultaneously presented options. This was partly motivated by observations in Kolling, Behrens, Mars, and Rushworth, Science, 336(6077), 95–98 (2012) (hereafter, KBMR) that these choice types are subserved by different circuits, with dorsal anterior cingulate (dACC) preferentially involved in foraging and ventromedial prefrontal cortex (vmPFC) preferentially involved in economic choice. To support this account, KBMR used fMRI to scan human subjects making either a foraging choice (between exploiting a current offer or swapping for potentially better rewards) or an economic choice (between two reward-probability pairs). This study found that dACC better tracked values pertaining to foraging, whereas vmPFC better tracked values pertaining to economic choice. We recently showed that dACC’s role in these foraging choices is better described by the difficulty of choosing than by foraging value, when correcting for choice biases and testing a sufficiently broad set of foraging values (Shenhav, Straccia, Cohen, & Botvinick Nature Neuroscience, 17(9), 1249–1254, 2014). Here, we extend these findings in 3 ways. First, we replicate our original finding with a larger sample and a task modified to address remaining methodological gaps between our previous experiments and that of KBMR. Second, we show that dACC activity is best accounted for by choice difficulty alone (rather than in combination with foraging value) during both foraging and economic choices. Third, we show that patterns of vmPFC activity, inverted relative to dACC, also suggest a common function across both choice types. Overall, we conclude that both regions are similarly engaged by foraging-like and economic choice.     

It’s Not You,It’s Me…No,Actually It’s You: Perceptions of What Makes a First Date Successful or Not

Early communication plays an important role in influencing the perceptions one has of an individual. The first form of in-person communication individuals often have with potential romantic partners is during the first date. This date tends to take on the form of a “dance” involving carefully orchestrated conversation and self-disclosures. What is said is certainly important, as are the behaviors exhibited by each member of the dyad. This study examined how individuals interpreted what potential romantic partners say and do during, or immediately following, the first date to get a sense of how they perceive these actions and words. Special attention was placed on the participants’ interpretations of whether or not their date was attracted to them. A survey was given to 390 participants, and many interesting differences were found between the genders. Certain behaviors, such as steering the conversation to the topic of sex signaled to men that their date was attracted to them. However, women looked for different behaviors to infer attraction on the part of their partner, such as mentioning future plans and kissing them goodbye. With a better understanding of how certain phrases and actions influence others, people can be more aware of the signals sent to others upon their pivotal initial encounters.     

Seeing the World Through “Pink‐Colored Glasses”: The Link Between Optimism and Pink

This study investigated optimism, which is considered a personality trait, from the grounded cognition perspective. Three experiments were conducted to investigate the association between pink and optimism. In Experiment 1A, 22 undergraduates (10 females; M_age = 23.68) were asked to classify words as optimistic or pessimistic as fast as possible. Half the words were presented in pink and half in black. Experiment 1B (N = 24; 14 females; M_age = 22.82) was identical to 1A except for the color of the words—black and light blue instead of pink—to rule out the possible influence of brightness. Experiment 2 exposed 144 participants (74 females; M_age = 25.18) to pink or yellow and then measured their optimism level. The findings for Experiments 1A and 1B indicated an association between pink and optimism regardless of brightness. Experiment 2 found that mere exposure to pink increased optimism levels for females. These results contribute to the dynamic view of personality, current views on optimism, and the growing literature on grounded cognition.     

Control Beliefs and Faith as Stress Moderators for Korean American Versus Caucasian American Protestants

Examined relationships among negative life events, four locus of control attributions (Internality, Powerful Others, Chance, and God Control), and psychological distress for Korean American versus Caucasian American Protestants. Negative events and Powerful Others beliefs were positively related to distress, whereas Internality was negatively related to distress. Ethnicity and God Control interacted: The relationship between God Control beliefs and anxiety was negative for Caucasians but positive for Koreans. Three-way interactions (Ethnicity × Locus of Control × Negative Events) also emerged. As Caucasians' Powerful Others beliefs increased, the positive relationship between negative events and depression became stronger; Koreans' Powerful Others beliefs had no such effect. As Caucasians' God Control beliefs increased, the negative event–depression relationship changed from positive to negative; the reverse was true for Koreans. Findings support the value of assessing ethnoculture and religiousness in stressful life events research.     

Do animals have rights?

A right, unlike an interest, is a valid claim, or potential claim, made by a moral agent, under principles that govern both the claimant and the target of the claim. Animals cannot be the bearers of rights because the concept of rights is essentially human; it is rooted in and has force within a human moral world.
