Preference for spatial cues in a non-storing songbird species

Male mammals typically outperform their conspecific females on spatial tasks. A sex difference in cues used to solve the task could underlie this performance difference as spatial ability is reliant on appropriate cue use. Although comparative studies of memory in food-storing and non-storing birds have examined species differences in cue preference, few studies have investigated differences in cue use within a species. In this study, we used a one-trial associative food-finding task to test for sex differences in cue use in the great tit, Parus major. Birds were trained to locate a food reward hidden in a well covered by a coloured cloth. To determine whether the colour of the cloth or the location of the well was learned during training, the birds were presented with three wells in the test phase: one in the original location, but covered by a cloth of a novel colour, a second in a new location covered with the original cloth and a third in a new location covered by a differently coloured cloth. Both sexes preferentially visited the well in the training location rather than either alternative. As great tits prefer colour cues over spatial cues in one-trial associative conditioning tasks, cue preference appears to be related to the task type rather than being species dependent.     

Self-Concept,Motivational Orientation,and Help-Seeking Behavior in Mathematics: A Study of Adults Returning to High School

The purpose of this study was to explore relations between mathematics achievement, self-concept, goal orientation, intrinsic motivation, and help-seeking behavior among adults studying for a high school diploma. Participants in this study were 145 adults (55 males and 90 females) enrolled in nine first year high school classes for adult students at five high schools in three cities in Norway. The age of the students varied from 18 to 52 years. Data were analyzed by means of structural equation modeling. The results indicate that mathematics self-concept in adult years build strongly on achievement in school years and that it is predictive of adult students’ goal orientation, intrinsic motivation, and learning strategies. Three weakly correlated dimensions of goal orientation predicted interest and help-seeking behavior in mathematics lessons differently.     

What determines the eyes' landing position in words?

The place at which the eyes first fixate in a word during continuous reading, called the preferred landing position (PLP), is usually located halfway between the beginning and the middle of the word. To propose a mechanism that might account for the off-center location of the PLP, six eye movement experiments were conducted using a lexical decision task (Experiment 1) and a stimulus bisection task (Experiments 2-6). The type of stimulus--linguistic (words and nonwords) versus nonlinguistic (strings of hashes, dotted lines, and solid lines)--and the stimulus presentation side (left vs. right) were manipulated. The results showed that (1) stimulus discreteness versus continuousness is an important factor in saccade computation and (2) PLP asymmetry can be explained in terms of attentional and/or oculomotor processes.     

Is surface dysgraphia tied to semantic impairment? Evidence from a case of semantic dementia

Recent models of lexical processing suggest that written spelling partly depends upon the semantic system. According to these models, a deterioration in word meanings would necessarily lead to a spelling impairment, especially for low-frequency and orthographically irregular words. We report a case study of a patient (MK) with semantic dementia who presents impairments in knowledge of word meanings and surface dysgraphia. By specifically identifying concepts that are still known or that are partially or completely deteriorated, we show that the patient's spelling deficit is highly correlated with word comprehension. These data confirm that surface dysgraphia is directly linked to the breakdown in semantic memory.     

Involvement of short-term memory in complex mental calculation

The aim of this study was to examine the involvement of the short-term memory system in complex mental addition by manipulating the phonological and visual similarity of two numbers to be added. The phonological similarity of the problems appeared to have a major effect on both speed and accuracy. However, the manipulation of visual similarity failed to have any measurable impact. This suggests that the phonological loop, rather than the visual-spatial sketch pad, would be used preferably for temporary storage of addends. An interpretation of these results in terms of the nature of the internal code underlying this task is discussed.     

To What Extent do we Hear Phonemic Contrasts in a Non-native Regional Variety? Tracking the Dynamics of Perceptual Processing with EEG

This combined ERP and behavioral experiment explores the dynamics of processing during the discrimination of vowels in a non-native regional variety. Southern listeners were presented with three word forms, two of which are encountered in both Standard and Southern French ([kot] and [kut]), whereas the third one exists in Standard but not Southern French ([kot]). EEG recordings suggest that all of the word pairs were discriminated by the listeners, although discrimination arose about 100ms later for the pairs which included the non-native word form than for those which contained word forms common to both French varieties. Behavioral data provide evidence that vowel discrimination is sensitive to the influence of the listeners’ native phonemic inventory at a late decisional stage of processing.     

A DISCOURSE ON SOPHOCLES: FREUD AND DETERMINISM

A study on the subjective experience of neuroleptic treatment is used as an example of research that employs psychoanalytic theory and methodology outside the clinical situation. Psychoanalytic tenets such as psychosexuality and the unconscious are highlighted, and the systematic study of internal reality is discussed with reference to the study on neuroleptics, the results of which are presented in extenso. Metapsychology is considered as a means for systematization, and self-reflexive countertransference analysis is seen as a means for fostering trustworthiness and reliability. The validity criteria discussed are clinical relevance, coherence, and originality (as distinct from merely confirming received theory). Value conflicts between academic and psychoanalytic scientific cultures are described with reference to the data of the specimen study. The concluding discussion includes a brief comparison of the time-limited interview method with long-term, clinical psychoanalytic inquiries.

“Flechsig's Brain science is the theory and Schreber's delusions are the practice of the same traumatic collapse of…subjectivity, of the gap separating bodily cause and symbolic effect. Schreber's point would seem to be that the elimination of the gap—the attempt to fill it with neuroanatomical knowledge—is nothing short of soul murder.” Eric Santner (1996), My own private Germany: Daniel Paul Schreber's secret history of modernity (p. 75)     

Effect of negative emotional content on attentional maintenance in working memory

ABSTRACT

Previous research has shown that emotional stimuli may interfere with working memory (WM) processes, but little is known about the process affected. Using a complex span task, the present study investigated the influence of processing negative emotional content on attentional maintenance in WM. In two experiments conducted under articulatory suppression, participants were asked to remember a series of five letters, each of which was followed by an image to be categorised. In half of the trials, the images were negative and in the other half, they were neutral. In both experiments, our results showed longer processing times for emotional stimuli than neutral stimuli, and lower memory performance when participants processed negative stimuli. We propose that emotional stimuli direct more attentional resources towards the processing component of the WM task, thereby reducing the storage capacity available for the items that are to be remembered.     

Respiratory feedback in the generation of emotion

This article reports two studies investigating the relationship between emotional feelings and respiration. In the first study, participants were asked to produce an emotion of either joy, anger, fear or sadness and to describe the breathing pattern that fit best with the generated emotion. Results revealed that breathing patterns reported during voluntary production of emotion were (a) comparable to those objectively recorded in psychophysiological experiments on emotion arousal, (b) consistently similar across individuals, and (c) clearly differentiated among joy, anger, fear, and sadness. A second study used breathing instructions based on Study 1's results to investigate the impact of the manipulation of respiration on emotional feeling state. A cover story was used so that participants could not guess the actual purpose of the study. This manipulation produced significant emotional feeling states that were differentiated according to the type of breathing pattern. The implications of these findings for emotion theories based on peripheral feedback and for emotion regulation are discussed.
