Metaphor priming in sentence production: Concrete pictures affect abstract language production

People speak metaphorically about abstract concepts—for instance, a person can be “full of love” or “have a lot of love to give.” Over the past decade, research has begun to focus on how metaphors are processed during language comprehension. Much of this work suggests that understanding a metaphorical expression involves activating brain and body systems involved in perception and motor control. However, no research to date has asked whether the same is true while speakers produce language. We address this gap using a sentence production task. Its results demonstrate that visually activating a concrete source domain can trigger the use of metaphorical language drawn from that same concrete domain, even in sentences that are thematically unrelated to the primes, a metaphorical priming effect. This effect suggests that conceptual metaphors play a part in language production. It also shows that activation in the perceptual system that is not part of an intended message can nevertheless influence sentence formulation.     

Salivary conditioning with antennal gustatory unconditioned stimulus in an insect

Classical conditioning of olfactory conditioning stimulus (CS) with gustatory unconditioned stimulus (US) in insects has been used as a pertinent model for elucidation of neural mechanisms underlying learning and memory. However, a conditioning system in which stable intracellular recordings from brain neurons are feasibly obtained while monitoring the conditioning effect has remained to be established. Recently, we found classical conditioning of salivation in cockroaches Periplaneta americana, in which an odor was associated with sucrose solution applied to the mouth, and this conditioning could be monitored by activities of salivary neurons. Application of gustatory US to the mouth, however, leads to feeding movement accompanying a movement of the brain that prevents stable recordings from brain neurons. Here we investigated whether a gustatory stimulus presented to an antenna could serve as an effective US for producing salivary conditioning. Presentation of sucrose or sodium chloride solution to an antenna induced salivation and also increased activities of salivary neurons. A single pairing trial of an odor with antennal presentation of sucrose or sodium chloride solution produced conditioning of salivation or of activities of salivary neurons. Five pairing trials led to a conditioning effect that lasted for one day. Water or tactile stimulus presented to an antenna was not effective for producing conditioning. The results demonstrate that gustatory US presented to an antenna is as effective as that presented to the mouth for producing salivary conditioning. This conditioning system provides a useful model for studying the neural basis of learning at the level of singly identifiable neurons.     

Minding Money: How Understanding of Value is Culturally Promoted

Adding to the issues of cognitive economics (Cortes and Londoño IPBS: Integrative Psychological &; Behavioral Science 43(2):178–184, 2009) and the social psychology of “shadow economics” (Salvatore et al. IPBS: Integrative Psychological &; Behavioral Science 43(2), 2009), the carrier of economic exchanges, money, plays a key role in children’s socialization in different societies. Money given to children, ‘pocket money,’ is a negotiated settlement between children’s social demands and those of their parents. I analyze such negotiations here on the basis of a concrete case of a Korean family in which the provision of pocket money given the child was inconsistent over time. The results indicate the social ecology of money use, in both children and their parents, sets the stage for value construction of the meaning of money.     

Individual differences in relatedness and individuality: An exploration of two constructs

Sociotropy and autonomy are two personality dimensions that relate to an individual's vulnerability to depression. Independent and interdependent self-construals are two distinctive cognitive formulations of the self derived from cross-cultural research. Both of these sets of constructs reflect self and other orientations. The purpose of the present study was to empirically examine the various factors that emerge when these two constructs are integrated. 652 participants responded to the Personal Style Inventory [Robins, C. J., Ladd, J., Welkowitz, J., Blaney, P. H., Diaz, R. & Kutcher, G. (1991). The Personal Style Inventory: Preliminary validation studies of new measures of sociotropy and autonomy. Journal of Psychopathology and Behavioral Assessment, 16, 277–300.], the Sociotropy-Autonomy Scale [Clark, D. A. & Beck, A. T. (1991). Personality factors in dysphoria: A psychometric refinement of Beck's Sociotropy-Autonomy Scale. Journal of Psychopathology and Behavioral Assessment, 13, 369–388.] and the Self-Construal Scale [Singelis, T. M. (1994). The measurement of independent and interdependent self-construals. Personality and Social Psychology Bulletin, 20, 580–591.]. Four factors emerged from a factor analysis conducted on the items of the three scales measuring sociotropy-autonomy and independent and interdependent self-construal. These four factors are discussed in the context of vulnerability to depression.     

Effects of acute simulated microgravity on nocturnal sleep, daytime vigilance, and psychomotor performance: comparison of horizontal and 6 degrees head-down bed rest

This study examined the effect of acute simulated microgravity on nocturnal sleep, daytime vigilance, and psychomotor performance. Each of 7 volunteers were maintained for 3 days of head-down and horizontal bed rest in a counter-balanced design. Assessment measures were polysomnographic recordings on the first night and performance on psychophysiological tasks on the second day involving subjective and objective vigilance, P300, simple reaction time tasks, and dual performance tasks. No clear difference in sleep structure was observed between the head-down and horizontal conditions, except for a slight decrease in Stage 4 for head-down. Both subjective and objective daytime vigilance, P300, and the simple RT task showed no statistical difference, although tracking performance on the dual task showed deterioration at 10:00 for the head-down condition. These results suggest that nocturnal sleep, daytime vigilance, and psychophysiological functions were not disturbed in head-down sleep conditions, although there was a mild deterioration of higher attentional function in the morning.     

The Maxwellian optics laboratory automation using a personal computer

The Maxwellian optical system described here is fully automated in both experimental control for psychophysical instrumentation and data gathering using a personal computer (PC) with simple interfacing and input/output processing. The system features PC-based high-speed noise-free liquid-crystal shutter control, automated light control, glow modulator tube control, and filter/wedge control. PC-based data gathering and data transfer to the mainframe via RS-232C based Teloeom are described.
