论相对于生产力的"自然破坏力"

从历史到现代,人类实践体系中总是不时地孕育出某种破坏性力量(本文称之为“自然破坏力”),这种破坏力与一直被视为实践积极成果的物质生产力密切相关,共同影响社会发展。以前我们仅仅正面地看待实践,遗忘了孕育出“自然破坏力”的实践的负面性。其实,引入“生产力”与“自然破坏力”的对立,才能使生产力和生产关系的理论对于现代发展更富有解释力。     

Military leaders and followers – do they have different decision styles?

There are five different, although not mutually exclusive, styles exhibited by military officers when making decisions: rational, intuitive, dependent, avoidant, and spontaneous ( Scott & Bruce, 1995 ). The purpose was to investigate if elected leaders of military planning teams had a different configuration of decision-making styles than their team members. Participants were 98 army captains organized in 16 brigade-level planning teams. The results indicate that team leaders tended to be more spontaneous and less rational, dependent and avoidant in their style configuration than their team members. One possible explanation is that the style configuration exhibited by many of the elected leaders comes through to others as forcefulness and decisiveness and that such a profile is in line with a general leadership culture. The results also provide support for the General Decision-Making Style inventory as a measurement of decision styles, because they suggest that the self-reports coincide with displayed, observable behavior.     

<Emphasis Type="Italic">Uh</Emphasis> and <Emphasis Type="Italic">Um</Emphasis> Revisited: Are They Interjections for Signaling Delay?

Clark and Fox Tree (2002) have presented empirical evidence, based primarily on the London–Lund corpus (LL; Svartvik & Quirk, 1980), that the fillers uh and um are conventional English words that signal a speaker’s intention to initiate a minor and a major delay, respectively. We present here empirical analyses of uh and um and of silent pauses (delays) immediately following them in six media interviews of Hillary Clinton. Our evidence indicates that uh and um cannot serve as signals of upcoming delay, let alone signal it differentially: In most cases, both uh and um were not followed by a silent pause, that is, there was no delay at all; the silent pauses that did occur after um were too short to be counted as major delays; finally, the distributions of durations of silent pauses after uh and um were almost entirely overlapping and could therefore not have served as reliable predictors for a listener. The discrepancies between Clark and Fox Tree’s findings and ours are largely a consequence of the fact that their LL analyses reflect the perceptions of professional coders, whereas our data were analyzed by means of acoustic measurements with the PRAAT software (www.praat.org). A comparison of our findings with those of O’Connell, Kowal, and Ageneau (2005) did not corroborate the hypothesis of Clark and Fox Tree that uh and um are interjections: Fillers occurred typically in initial, interjections in medial positions; fillers did not constitute an integral turn by themselves, whereas interjections did; fillers never initiated cited speech, whereas interjections did; and fillers did not signal emotion, whereas interjections did. Clark and Fox Tree’s analyses were embedded within a theory of ideal delivery that we find inappropriate for the explication of these phenomena.     

A Wandering Mind is Not Always a Creative Mind: How Thought Dynamics Explain the Relationship between Mind Wandering and Creativity

A wandering mind is not always a creative mind. Anecdotes about ideas spontaneously entering awareness during walks, showers, and other off-task activities are plenty. The science behind it, however, is still inconclusive. Creativity might result from how thought context—whether thoughts are on-task or off-task—relates to thought dynamics—how thoughts unfold. To explore this, study 1 (n = 85) surveyed creative professionals about a single idea they had earlier in the day. The spontaneity of thoughts positively correlated with self-reported creativity, whereas off-task thoughts or doing something else did not. Study 2 (n = 180) replicated these findings in a student sample during an idea generation task and added that free movement of thoughts also correlates with self-reported originality during idea generation. As indicated by expert ratings, no relationship of thought dynamics and thought context was found with population-level creativity. Herewith, this study suggests that thought dynamics, rather than thought context, explain the often suggested relationship between mind wandering and creativity.     

Spontaneous Interpersonal Coordination in Stepping and Autistic-Like Traits1

Spontaneous behavior, matching that of others, is influenced by various social factors. Mimicking and synchronizing with others' behaviors can facilitate the development of harmonious relationships. This study examined whether the level of autistic-like traits in a non-clinical population influences the spontaneous-behavioral coordination of a dyad's stepping-on-the-spot movements. The strength of spontaneous stepping synchronization was negatively correlated with levels of autistic-like traits when participants faced one another, and no synchronization was observed for individuals with high levels of autistic-like traits. The deficit in spontaneous interpersonal behaviour-matching among individuals with high levels of autistic-like traits is discussed as a potential source of their poor social-communication abilities.     

Contextual effects on prejudiced attitudes: When the presence of others leads to more egalitarian responses

In the present paper, we tested the hypothesis that the physical presence of other ingroup members may ameliorate Whites’ spontaneous affective responses toward Blacks. Results of Study 1 demonstrated that IAT-assessed attitudes toward Blacks were indeed less negative when participants were tested in small groups rather than individually. Study 2 shed light on the underlying processes by demonstrating that respondents at the presence of others displayed increased accessibility to egalitarian-related concepts after Black primes, as compared to respondents tested individually. Overall, results point to the wide malleability of spontaneous affective responses and to the possibility that contextual factors, like the presence of other individuals, might automatically activate egalitarians goals. Results are discussed in relation to current models of automatic intergroup bias and preconscious control over it.

Spontaneous rotation of nanoparticles in a medium

In many experiments, the effects of spontaneous rotation of nanoparticles in a medium have been observed. In the article it has been shown that the reason for the spontaneous rotation of nanoparticles in a medium may be due to an increase in rotational entropy that accompanies the increasing rotational frequencies of the nanoparticles. An equation describing the rotational motion of the nanoparticles in a medium is obtained and its solution is found. It is shown that the formation of a large number of randomly oriented nanocrystals may be a reason for the forming of an amorphous phase upon cooling a melt.     

Why are negative behaviours likely to be immediately invoked traits? The effects of valence and frequency on spontaneous trait inferences

People make trait inferences immediately when observing others’ behaviours. Previous studies reported that this spontaneous trait inference (STI) occurs more strongly from negative behaviours than from positive behaviours. However, what is responsible for this negativity bias in STI is unclear. In this study, two experiments investigated the effects of valence (an event's affective positivity or negativity) and frequency (how frequently the behaviour is observed in everyday life) on the occurrence of STI using an adapted version of a savings‐in‐relearning paradigm. Experiment 1 revealed that only valence affected the frequent occurrence of STI. In addition, the instructions to suppress impression formation or to focus attention on an actor's face made no difference to the results. In Experiment 2, the negativity bias in STIs was shown a week after exposure to the behavioural stimuli. These results suggest that the negativity bias in STIs occurs robustly, and the negative valence of observed behaviour is mostly responsible for the negativity bias in STI. The importance of immediate categorization of negative stimuli is discussed in terms of ecological priority.     

Spontaneous Trait Associations and the Case of the Superstitious Banana

We explored whether spontaneous trait transference (STT) occurs in cases where inanimate objects, rather than human bystanders, are presented in the context of trait-implicative behavior. The results provide a vivid demonstration of the associability of primed trait constructs by demonstrating STT to inanimate objects to which one does not normally attribute traits (e.g., superstitious being associated with a banana). This finding is consistent with the notion that the trait associations involved in STT are formed independent of person perception processes. The implications of this finding for the types of associative processes exposed by the popular savings in relearning methodology are discussed.
