Beyond the Grand Illusion: What Change Blindness Really Teaches Us About Vision

Experiments on scene perception and change blindness suggest that the visual system does not construct detailed internal models of a scene. These experiments therefore call into doubt the traditional view that vision is a process in which detailed representations of the environment must be constructed. The non-existence of such detailed representations, however, does not entail that we do not perceive the detailed environment. The “grand illusion hypothesis” that our visual world is an illusion rests on (1) a problematic “reconstructionist” conception of vision, and (2) a misconception about the character of perceptual experience.     

Attending to objects: costs or benefits?

The single-object advantage is said to occur when performance is faster and/or more accurate when the two targets to be compared appear on one object than when they appear on two different objects. The single-object advantage has been interpreted to suggest that attention can select objects rather than unparsed regions of visual space. In five experiments we explored whether directing attention to one object rather than two objects produces a benefit or a minor cost. Participants were required to compare two target features that belonged to one object, to two objects, or did not belong to any object. In addition, we varied the relevance to the task of object-related global information, such as symmetry of the object and perceptual cluttering of the background. Results showed that attending to one object in comparison to attending to no object produced a benefit only when object-related global information was relevant to the task. In contrast, when object-related global information was irrelevant to the task, attending to one object produced a cost. Thus, it can be concluded that attending to an object does not produce an absolute benefit, but rather produces a smaller cost than attending to two objects.     

Psychodynamik und neurophysiologischer Befund bei einem Patienten mit einer zwanghaften Lesestörung

The present single case study is aimed to investigate neuro-physiological correlates of checking and ordering compulsions in a 40 years old patient suffering from obsessive-compulsive disorder (OCD) by means of the functional magnetic resonance imaging (fMRI) method. After the presentation of the psychogenesis and psychodynamic of the OCD case, the cardinal symptom, a compulsive reading disturbance, is described in detail. Based on the symptom analysis eight different texts, hierarchically arranged by their degrees of difficulty were composed and presented to the patient for reading during fMRI. The results of the fMRI during symptom provocation display significant increase of activation in fronto-thalamic-cortical neural circuits with the occurence of compulsive reading disturbances compared with unproblematic texts and with the reading of a control subject. The findings are discussed in relation to the neurobiologic literature as well as to an object-psychological model of the OCD.     

The consequences of job-related pressure for self-determined teaching

In education, there is a common understanding that teachers contribute significantly to the motivation of their pupils. However, the instructors’ own psychological needs in the tradition of the Self-determination Theory (Ryan and Deci Self-determination theory: basic psychological needs in motivation, development, and wellness, Guilford Press, New York, 2017) are often overshadowed and undermined by external as well as internal processes. Present research so far has solely focused on the scientific perception of this problem, neglecting the viewpoint of the subjects—the teachers. In this paper, 732 secondary school teachers in Austria were surveyed; data were assessed through questionnaires regarding basic psychological needs, perceived job-related pressure, team orientation as well as self-efficacy and proactive attitude. The results emphasize the impact of job-related pressure on the motivation of teachers and the importance of psychological needs satisfaction in teaching with special focus on autonomy. Yet, it is this feature that is often neglected in Austrian educational politics. Consequently, students’ motivation can be improved through the enhancement of teachers’ occupational psychological needs, which in turn relies on the reduction of unnecessary controlling elements and strengthens their work-related autonomy.

     

Some sources for a history of English Socinianism a bibliography of 17th century English Socinian writings

Conclusion In 1697, the Presbyterian, William Bates, presented an address, on behalf of some dissenting ministers, to William of Orange. In this, he called for measures against the Socinians and Deists, and, in particular, for the banning of the publication of Socinian works. Bates' address was published in JOHN HOWE, Sermon Preech'd on the Day of Thanksgiving (1698). On 17th February, 1698, the House of Commons presented an address to the King, We do further, in all humility, beseech Your Majesty, that Your Majesty would give such effectual order, as to Your Royal Wisdom shall seem fit, for the suppressing all pernicious books and pamphlets, which contain in them impious doctrines against the Holy Trinity, and other fundamental articles of our Faith, tending to the subversion of the Christian Religion; and that the authors and publishers thereof may be discounted and punished.The statute 9 and 19 William III, c. 32, An Act for the more effectual suppressing of Blasphemy and Profaneness, accepted these requests. It prohibited the writing, publishing and teaching of doctrines that were contrary to the Trinity, Christian truth or the divine authority of the Old and the New Testaments.It should be noted that the Toleration Act of 1689 does not extend tolerance to, amongst others, those who deny the dogma of the Trinity. It was not until 1813 that the Unitarians were free to practise their cult. The Trinity Act (An Act to relieve persons who impugn the Doctrine of the Holy Trinity from certain Penalties. 53 Geo. III, c. 160) of that year exempted the Unitarians from the penalties laid down by the Toleration Act and by the Blasphemy Act quoted above     

Health anxiety and hypochondriasis in the light of DSM-5

Background: In the DSM-5, the diagnosis of hypochondriasis was replaced by two new diagnositic entities: somatic symptom disorder (SSD) and illness anxiety disorder (IAD). Both diagnoses share high health anxiety as a common criterion, but additonal somatic symptoms are only required for SSD but not IAD. Design: Our aim was to provide empirical evidence for the validity of these new diagnoses using data from a case–control study of highly health-anxious (n = 96), depressed (n = 52), and healthy (n = 52) individuals. Results: The individuals originally diagnosed as DSM-IV hypochondriasis predominantly met criteria for SSD (74%) and rarely for IAD (26%). Individuals with SSD were more impaired, had more often comorbid panic and generalized anxiety disorders, and had more medical consultations as those with IAD. Yet, no significant differences were found between SSD and IAD with regard to levels of health anxiety, other hypochondriacial characteristics, illness behavior, somatic symptom attributions, and physical concerns, whereas both groups differed significantly from clinical and healthy controls in all of these variables. Conclusion: These results do not support the proposed splitting of health anxiety/hypochondriasis into two diagnoses. Further validation studies with larger samples and additional control groups are warranted to prove the validity of the new diagnoses.     

Impact of Genetic Counseling in Women with a Family History of Breast Cancer in Italy

As the impact of breast cancer (BC) risk assessment in asymptomatic women with a family history of BC had never been explored in Italy, we performed a study on a retrospective series of women who had undergone BC risk assessment. To this aim, a semi-structured telephone interview was administered to 82 women. Most participants considered the information received as clear (96.2 %) and helpful (76.8 %). Thirty-eight (46.3 %) stated that their perceived risk of BC had changed after the counseling: for 40.2 % it had decreased, for 6.1 % increased; however, women highly overestimating their risk at the baseline (≥4-fold) failed to show improvements in risk perception accuracy. Sixty-six women (80.5 %) stated they had followed the recommended surveillance, while 19.5 % had not, mainly due to difficulties in arranging examinations. Most women (89.0 %) had shared the information with their relatives, with 57.3 % reporting other family members had undertaken the recommended surveillance. BC risk assessment was associated with high rates of satisfaction and had a favorable impact on risk perception in a subgroup of women. The impact on surveillance adhesion extended to relatives. Organized programs for identification and surveillance may help identify a larger fraction of at-risk women and overcome the reported difficulties in arranging surveillance.     

Spontaneous non‐verbal counting in toddlers

A wealth of studies have investigated numerical abilities in infants and in children aged 3 or above, but research on pre‐counting toddlers is sparse. Here we devised a novel version of an imitation task that was previously used to assess spontaneous focusing on numerosity (i.e. the predisposition to grasp numerical properties of the environment) to assess whether pre‐counters would spontaneously deploy sequential (item‐by‐item) enumeration and whether this ability would rely on the object tracking system (OTS) or on the approximate number system (ANS). Two‐and‐a‐half‐year‐olds watched the experimenter performing one‐by‐one insertion of ‘food tokens’ into an opaque animal puppet and then were asked to imitate the puppet‐feeding behavior. The number of tokens varied between 1 and 6 and each numerosity was presented many times to obtain a distribution of responses during imitation. Many children demonstrated attention to the numerosity of the food tokens despite the lack of any explicit cueing to the number dimension. Most notably, the response distributions centered on the target numerosities and showed the classic variability signature that is attributed to the ANS. These results are consistent with previous studies on sequential enumeration in non‐human primates and suggest that pre‐counting children are capable of sequentially updating the numerosity of non‐visible sets through additive operations and hold it in memory for reproducing the observed behavior.
