Seeing red primes tomato: evidence for comparable priming from colour and colour name primes to semantically related word targets

There is ample evidence that an independent processing stream exists that subserves the perception and appreciation of colour. Neurophysiological research has identified separate brain mechanisms for the processing of wavelength and colour, and neuropsychological studies have revealed selective colour disorders, such as achromatopsia, colour agnosia, and colour anomia. The aim of the present study is to investigate whether the perception of colour may, despite its independent processing, influence other cognitive functions. Specifically, we investigate the possibility that the perception of a colour influences higher order processes such as the activation of semantically related concepts. We designed an associative priming task involving a colour prime (e.g. a red patch or the word RED) and a lexical decision response to a semantically related (‘tomato’ vs. ‘timato’) or unrelated (‘grass’ vs. ‘griss’) word target. The results of this experiment indicate that there is comparable facilitation of accessing colour-related semantics through the perception of a colour or the reading of a colour name. This suggests that colour has a direct effect on higher order level, cognitive processing. These results are discussed in terms of current models of colour processing.     

Psychobiology of altered states of consciousness

The article reviews the current knowledge regarding altered states of consciousness (ASC) (a) occurring spontaneously, (b) evoked by physical and physiological stimulation, (c) induced by psychological means, and (d) caused by diseases. The emphasis is laid on psychological and neurobiological approaches. The phenomenological analysis of the multiple ASC resulted in 4 dimensions by which they can be characterized: activation, awareness span, self-awareness, and sensory dynamics. The neurophysiological approach revealed that the different states of consciousness are mainly brought about by a compromised brain structure, transient changes in brain dynamics (disconnectivity), and neurochemical and metabolic processes. Besides these severe alterations, environmental stimuli, mental practices, and techniques of self-control can also temporarily alter brain functioning and conscious experience.     

Semantics and the computational paradigm in cognitive psychology

There is a prevalent notion among cognitive scientists and philosophers of mind that computers are merely formal symbol manipulators, performing the actions they do solely on the basis of the syntactic properties of the symbols they manipulate. This view of computers has allowed some philosophers to divorce semantics from computational explanations. Semantic content, then, becomes something one adds to computational explanations to get psychological explanations. Other philosophers, such as Stephen Stich, have taken a stronger view, advocating doing away with semantics entirely. This paper argues that a correct account of computation requires us to attribute content to computational processes in order to explain which functions are being computed. This entails that computational psychology must countenance mental representations. Since anti-semantic positions are incompatible with computational psychology thus construed, they ought to be rejected. Lastly, I argue that in an important sense, computers are not formal symbol manipulators.     

Current status of intrathecal antifibrinolytic therapy with p-aminomethylbenzoic acid (PAMBA) in subarachnoid hemorrhages

The blood-brain barrier is barely affected by slight or moderate subarachnoidal bleeding so that the p-aminomethylbenzoic acid (PAMBA) administered systemically for antifibrinolytic therapy does not attain the continuous level necessary in the cerebrospinal fluid. Thus the antifibrinolytic agent should be applied intrathecally because this would totally inhibit fibrinolytic activity in cerebrospinal fluid containing blood and during the wound healing of ruptured aneurysmas. The improvement in wound healing reduces the occurrence of rebleeding, especially during the first 10 days, and improves conditions for successful surgical intervention.     

Work-related goal appraisals and stress during the transition from education to work

People's personal goals interact with their life situations in many ways. This study examined the appraisals of personal goals during a transition from education to work and their interplay with stress in different domains of life. Finnish young adults (N = 265, 60% female) reported on their goals in the work domain, and related appraisals of importance, attainability, and progress, and the amount of stress they experienced with regard to economic situation, time, and work. The results showed that those individuals who appraised their work goals as important, attainable and progressing well, benefited from their goal striving as evidenced in less stress in all three domains. Moreover, individuals who initially experienced elevated stress levels due to their economic and work situation adapted their work-related goals, such that they later set goals which were more attainable and showed better progress. For these individuals, pursuing work goals remained highly important, whereas for others work goal importance declined.     

How sex puts you in gendered shoes: sexuality-priming leads to gender-based self-perception and behavior

Scripts for sexual behavior dictate that women be submissive and tender and that men be assertive and dominant, reflecting the stereotypical view of women as communal and of men as agentic. Six experiments tested the hypothesis that exposure to sexuality cues causes men's and women's momentary self-perceptions and concomitant behavior to become more gender-typical. Using both pictorial and verbal prime materials that were presented both supraliminally and subliminally, we found that sex-priming strengthened gender-based self-perceptions (i.e., faster self-categorization as a woman or man; Study 1), heightened identification with one's own gender (Study 2), increased gender self-stereotyping (Study 3), and elicited greater submissiveness in women's behavior and greater assertiveness in men's behavior (Studies 4 and 5). These findings indicate that sex-priming causes self-perception and social behavior to become "attuned" to gender stereotypes. Study 6 demonstrated that these sex-priming effects can be eliminated by modern gender role primes. The potentially detrimental effects of sex-priming and possible countermeasures are discussed.     

Reliable facial muscle activation enhances recognizability and credibility of emotional expression

We tested Ekman's (2003) suggestion that movements of a small number of reliable facial muscles are particularly trustworthy cues to experienced emotion because they tend to be difficult to produce voluntarily. On the basis of theoretical predictions, we identified two subsets of facial action units (AUs): reliable AUs and versatile AUs. A survey on the controllability of facial AUs confirmed that reliable AUs indeed seem more difficult to control than versatile AUs, although the distinction between the two sets of AUs should be understood as a difference in degree of controllability rather than a discrete categorization. Professional actors enacted a series of emotional states using method acting techniques, and their facial expressions were rated by independent judges. The effect of the two subsets of AUs (reliable AUs and versatile AUs) on identification of the emotion conveyed, its perceived authenticity, and perceived intensity was investigated. Activation of the reliable AUs had a stronger effect than that of versatile AUs on the identification, perceived authenticity, and perceived intensity of the emotion expressed. We found little evidence, however, for specific links between individual AUs and particular emotion categories. We conclude that reliable AUs may indeed convey trustworthy information about emotional processes but that most of these AUs are likely to be shared by several emotions rather than providing information about specific emotions. This study also suggests that the issue of reliable facial muscles may generalize beyond the Duchenne smile.     

Sport psychology group consultation using social networking web sites

A social networking Web site, Facebook, was used to deliver long-term sport psychology consultation services to student-athletes (i.e., soccer players) in 30- to 60-min weekly sessions. Additional short-term team building, group cohesion, communication, anger management, injury rehabilitation, mental toughness, commitment, and leadership workshops were provided. Cohesion and overall relationships between both the student-athletes and the sport psychology consultants benefited from this process. Social networking Web sites offer a practical way of providing sport psychology consulting services that does not require use of major resources.
