An experiment is reported testing the idea that spatial selective attention operates like the beam of a spotlight. Subjects made speeded orientation judgements to alphanumeric characters that could appear at an upper or lower display location. Letters tended (p = 0.8) to occur at one location, while digits tended to occur at the other. Alphanumeric category was pre-cued (p = 0.8). Response times were faster for cued than uncued items. For cued items subjects were faster at the likely location for a cued item. For uncued items this was reversed, with faster responding at the likely location for an uncued item. Hence, location selectivity reflected location probability for each category regardless of short-term expectancy concerning stimulus category. These data are incompatible with a simple spotlight view of spatial selective attention. Alternative explanations, including a modified two-stage spotlight model, were considered.

The Continuum

AbstractEven though the outcome of the perception of phonological patterns is categorical, this process might still arise from continuous dynamics. Here, we propose a unified dynamical account of three types of behavior that are usually studied in isolation: short-term perceptual competition, long-term perceptual habituation, and even longer-term perceptual learning. We develop a model and test its predictions in two speech identification tasks on an acoustic continuum between the French words [sɛp] and [stɛp]. When presenting stimuli sequentially from one end of the continuum to the other, we found that the presentation order systematically changed the position of the perceptual switch from one word to the other. We also found that response times were slower and more variable around this perceptual switch, regardless of its position on the acoustic continuum. And, throughout the experiment, participants became more sensitive to small acoustic differences between stimuli. Our model can account for these results and for a surprising finding, namely that the initial presentation order affected responses even late in the experiment. Overall, our results point to the importance of the relation between fast processes responsible for competition, and slow processes responsible for habituation and learning in explaining how listeners can perceive speech categorically in a way that is both flexible and robust.

<p>Previous research has shown that there may be an association between affect (negative vs. positive) and vertical position (up vs. down) of stimuli. The following research aimed to investigate whether individuals show spatial biases, either up or down, when asked to respond to neutral targets after seeing valenced faces. The research also aimed to investigate what impact manipulating automatic facial mimicry responses would have on response times. The research was conducted over three experiments. In Experiment 1, participants responded to neutral targets in either high or low vertical positions on a computer screen that were preceded by happy and sad schematic faces. There were two facial manipulation conditions. One group held a straw between their lips to inhibit smiling and another group held a straw between their teeth to facilitate smiling. A third group performed the response task without a straw (control condition). The procedure of Experiment 2 was identical to Experiment 1 except the happy and sad schematic faces had additional internal facial features (noses, eyebrows) that varied across trials. For both Experiment 1 and 2, targets preceded by a happy face were responded to significantly faster. In Experiment 3, the procedure was identical to Experiments 1 and 2, except photographic images of happy, neutral, and sad expressions were used. Participants were significantly faster to respond to targets in the high vertical position. Participants were also faster to respond to targets in the control (no straw) condition than the other two straw conditions. In the inhibition smiling condition, participants were faster to respond to targets in the high vertical position than low vertical position after seeing a happy or neutral face. These findings indicate that there may be an association between valenced faces and vertical selective attention that is consistent with orientational metaphors (positive = up), but further research is needed to clarify this.</p>

When do causal attribution and counterfactual thinking facilitate one another, and when do the two responses overlap? Undergraduates (N = 78) both explained and undid, in each of two orders, events that were described either with their potential causes or not. The time to perform either response was recorded. Overall, mutation response times were shorter when performed after an attribution was made than before, while attribution response times did not vary as a consequence of sequence. Depending on whether the causes of the target events were described in the scenario or not, respondents undid the actor and assigned causality to another antecedent, or pointed to the actor for both responses. These findings suggest that counterfactual mutation is most likely to be facilitated by attribution, and that mutation and attribution responses are most likely to overlap when no information about potential causes of the event is provided.

Abstract. Folk wisdom tells us that additional time to make a decision helps us to refrain from the first impulse to take the bird in the hand. However, the question why the time to decide plays an important role is still unanswered. Here we distinguish two explanations, one based on a bias in value accumulation that has to be overcome with time, the other based on cognitive control processes that need time to set in. In an intertemporal decision task, we use mouse tracking to study participants’ responses to options’ values and delays which were presented sequentially. We find that the information about options’ delays does indeed lead to an immediate bias that is controlled afterwards, matching the prediction of control processes needed to counter initial impulses. Hence, by using a dynamic measure, we provide insight into the processes underlying short-term oriented choices in intertemporal decision making.

Hidden “holes” in the capital of banks and the supply of credit to the real sector of economy

Our analysis documents that the existence of hidden “holes” in the capital of not yet failed banks - while creating intertemporal pressure on the actual level of capital - leads to changing of maturity of loans supplied rather than to contracting of their volume. Long-term loans decrease, whereas short-term loans rise - and, what is most remarkably, by approximately the same amounts. Standardly, the higher the maturity of loans the higher the credit risk and, thus, the more loan loss reserves (LLP) banks are forced to create, increasing the pressure on capital. Banks that already hide “holes” in the capital, but have not yet faced with license withdrawal, must possess strong incentives to shorten the maturity of supplied loans. On the one hand, it raises the turnovers of LLP and facilitates the flexibility of capital management; on the other hand, it allows increasing the speed of shifting of attracted deposits to loans to related parties in domestic or foreign jurisdictions. This enlarges the potential size of ex post revealed “hole” in the capital and, therefore, allows us to assume that not every loan might be viewed as a good for the economy: excessive short-term and insufficient long-term loans can produce the source for future losses.

Basically a natural partnership will achieve its goal if mutual requirements, mutual reinforcement, and mutual benefit can be maintained and made a strong fundamental commitment among partners. Nevertheless the development seems very slow. The cause is the presence of specific and different conditions and structure factors compared to other countries. Along with that, we still encounter various forms of gaps, such as inequality among regions, among income groups, between sectors, among economic actors, and so forth. The next problem is that in business entities including cooperatives and micro and small enterprises in running their business activities requires business partnerships with medium and large enterprises in order to improve business performance and business scale. While on the other hand our economic conditions and structures are not yet fully conducive to fostering partnerships based on purely business considerations or competitive market motivations but the business partnership of the foundation is strong enough in our country's constitution. Partnerships will work if partners are equally benefiting. Our concept of partnership is like that, although in the short term, there is a party or a party benefiting more from the other side.

ABSTRACT Whether the short-term regulation of thyroidal protein synthesis by TSH occurs at the transcriptional or the translational level was tested by measuring the effect of actinomycin D (act D) on the TSH-induced stimulation of L-14C-leucine incorporation into the thyroidal proteins of rats. TSH was injected 6 h before the rats were killed. The thyroid glands were then removed and incubated in vitro in the presence of L-14C-leucine for 2 h. The pronounced stimulation of leucine incorporation in the TSH-treated animals was depressed as compared with controls but still significant even when the animals had been pre-treated with 100 μg act D 24 and 7 h before sacrifice. On the other hand, act D strongly decreased incorporation of 3H-uridine into RNA. Short-term regulation of thyroidal protein synthesis by TSH appears to be partly but not wholly dependent on neosynthesis of RNA. Hence regulation may partly occur at the translation level of protein synthesis.

Trait Impulsivity

Trait impulsivity has long been proposed to play a role in aggression, but the results across studies have been mixed. One possible explanation for the mixed results is that impulsivity is a multifaceted construct and some, but not all, facets are related to aggression. The goal of the current meta-analysis was to determine the relation between the different facets of impulsivity (i.e., negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking) and aggression. The results from 93 papers with 105 unique samples (N = 36, 215) showed significant and small-to-medium correlations between each facet of impulsivity and aggression across several different forms of aggression, with more impulsivity being associated with more aggression. Moreover, negative urgency (r = .24, 95% [.18, .29]), positive urgency (r = .34, 95% [.19, .44]), and lack of premeditation (r = .23, 95% [.20, .26]) had significantly stronger associations with aggression than the other scales (rs &lt; .18). Two-stage meta-analytic structural equation modeling showed that these effects were not due to overlap among facets of impulsivity. These results help advance the field of aggression research by clarifying the role of impulsivity and may be of interest to researchers and practitioners in several disciplines.
