Becoming a face expert

Expertise in recognizing facial identity, and, in particular, sensitivity to subtle differences in the spacing among facial features, improves into adolescence. To assess the influence of experience, we tested adults and 8-year-olds with faces differing only in the spacing of facial features. Stimuli were human adult, human 8-year-old, and monkey faces. We show that adults' expertise is shaped by experience: They were 9% more accurate in seeing differences in the spacing of features in upright human faces than in upright monkey faces. Eight-year-olds were 14% less accurate than adults for both human and monkey faces (Experiment 1), and their accuracy for human faces was not higher for children's faces than for adults' faces (Experiment 2). The results indicate that improvements in face recognition after age 8 are not related to experience with human faces and may be related to general improvements in memory or in perception (e.g., hyperacuity and spatial integration).     

Paranormal and Religious Believers Are More Prone to Illusory Face Perception than Skeptics and Non‐believers

Illusory face perception, a tendency to find human‐like faces where none are actually present in, for example, artifacts or scenery, is a common phenomenon that occasionally enters the public eye. We used two tests (N = 47) to analyze the relationship between paranormal and religious beliefs and illusory face perception. In a detection task, the participants detected face‐like features from pictures of scenery and landscapes with and without face‐like areas and, in a rating task, evaluated the face‐likeness and emotionality of these areas. Believer groups were better at identifying the previously defined face‐like regions in the images but were also prone to false alarms. Signal detection analysis revealed that believers had more liberal answering criteria than skeptics, but the actual detection sensitivity did not differ. The paranormal believers also evaluated the artifact faces as more face‐like and emotional than the skeptics, and a similar trend was found between religious and non‐religious people.

Evidence of the origin of specific spontaneous head turns during intertrial intervals

Direction and the frequency of spontaneous head movements during the ITIs following forward and backward paired trials were compared to an acquisition of a conditioned orienting (alpha) response directed to the side of the tone source. The head movements were analyzed from video recordings using classification of head turns to preferred and to nonpreferred directions. The results showed a significant increase in the alpha responses during the forward paired conditioning to the preferred direction and rapid extinction during the subsequent backward conditioning sessions. Spontaneous head movements during the ITIs increased to the same preferred direction as the conditioned alpha responses. The results of this experiment suggest that the response initially elicited by the CS can later appear as “spontaneous,” instrumental behavior, the form and the nature of which is determined by the characteristics of the conditioned alpha response developing as a result of classical conditioning.     

The chicken and the egg: a hindsight view of therapy

In this paper the authors suggest that instead of holding the view that the sequence of therapy follows the path of first interviewing and gathering data, then understanding and finally intervening on the basis of what is thought to be the cause of the problem, we could benefit from recognizing that the reverse view is equally plausible. According to this reverse view, which the authors call hindsight, therapists, unaware of it themselves, first come up with interventions and then, in hindsight, create explanations or particular ways of understanding problems in order to make their interventions seem rational and justifiable. A number of factors influencing therapists' choice of interventions are explored. Finally some potential advantages of the hindsight view are examined.     

Mobile technologies in use by those participating in Lutheran confirmation training in Finland

Abstract

This article focuses on the study of where mobile devices and social media tools are taken into consideration in the Finnish confirmation training entity as a new opportunity to work together. The research is based on the ethnographical method. The data was collected by observation in two confirmation training camp periods and interviewing confirmation training participants. The aim was to find out ways mobile devices were exploited in confirmation training pedagogy, how adolescents reacted to such mobile device use and how adolescents described their personal mobile device use. The research material is analysed by inductive content analysis. The findings are discussed in the theoretical context of the communities of practice (CoPs), originally formed by Lave and Wenger . According to the results, mobile device use, in the confirmation training programme did not seem to be that special for adolescents. At the same time, the youth considered it important to have the possibility to use mobile devices according to their own preferences. Using mobile devices in confirmation training challenged the traditional CoP setting, as adolescents used mobile technology more in their own way, being familiar with it in their earlier virtual communities of practice (VCoPs), instead of the plans of the workers of confirmation training.     

Conceptions about the mind-body problem and their relations to afterlife beliefs,paranormal beliefs,religiosity, and ontological confusions

We examined lay people’s conceptions about the relationship between mind and body and their correlates. In Study 1, a web survey (N = 850) of reflective dualistic, emergentistic, and monistic perceptions of the mind-body relationship, afterlife beliefs (i.e., common sense dualism), religiosity, paranormal beliefs, and ontological confusions about physical, biological, and psychological phenomena was conducted. In Study 2 (N = 73), we examined implicit ontological confusions and their relations to afterlife beliefs, paranormal beliefs, and religiosity. Correlation and regression analyses showed that reflective dualism, afterlife beliefs, paranormal beliefs, and religiosity were strongly and positively related and that reflective dualism and afterlife beliefs mediated the relationship between ontological confusions and religious and paranormal beliefs. The results elucidate the contention that dualism is a manifestation of universal cognitive processes related to intuitions about physical, biological, and psychological phenomena by showing that especially individuals who confuse the distinctive attributes of these phenomena tend to set the mind apart from the body.     

Auditory perception of speech and speech sounds in recent and recovered cases of aphasia

Auditory perception of speech and speech sounds was examined in three groups of patients with cerebral damage in the dominant hemisphere. Two groups consisted of brain-injured war veterans, one group of patients with high-frequency hearing loss and the other, a group of patients with a flat hearing loss. The third group consisted of patients with recent cerebral infarcts due to vascular occlusion of the middle cerebral and internal carotid artery. Word and phoneme discrimination as well as phoneme confusions in incorrect responses were analyzed from conventional speech audiometry tests with bisyllabic Finnish words fed close to the speech reception threshold of the patient. The results were compared with those of a control group with no cerebral disorders and normal hearing. The speech discrimination scores of veterans with high-frequency hearing loss and patients with recent cerebral infarcts were some 15–20% lower than those of controls or veterans with flat hearing loss. Speech sound feature discrimination, analyzed in terms of place of articulation and distinctive features, was distorted especially in cases of recent cerebral infarcts, whereas general information transmission of phonemes was more impaired in patients with high-frequency hearing loss.     

Human values and non‐adherence to doctors' instructions across Europe

This study examines the relationships between human values and patient non‐adherence. Two types of non‐adherence are studied: non‐adherent views and non‐adherent behavior in response to doctor's instructions. The study uses data from the European Social Survey Round 2 from 14 countries: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Iceland, Luxembourg, Netherlands, Norway, Poland, Sweden, and Switzerland. Correlation analyses and multiple logistic regression analyses were conducted both using the pooled data from these 14 countries and within countries. The sample size ranged from n = 20,012 to n = 21,600 in the analyses of pooled data. Human values were found to be associated with non‐adherence. As hypothesized, endorsing openness‐to‐change values (vs. conservation values) was positively related to non‐adherent views and behavior.     

Hippocampal theta (3-8Hz) activity during classical eyeblink conditioning in rabbits

In 1978, Berry and Thompson showed that the amount of theta (3–8 Hz) activity in the spontaneous hippocampal EEG predicted learning rate in subsequent eyeblink conditioning in rabbits. More recently, the absence of theta activity during the training trial has been shown to have a detrimental effect on learning rate. Here, we aimed to further explore the relationship between theta activity and classical eyeblink conditioning by determining how the relative power of hippocampal theta activity [theta/(theta + delta) ratio] changes during both unpaired control and paired training phases. We found that animals with a higher hippocampal theta ratio immediately before conditioning learned faster and also that in these animals the theta ratio was higher throughout both experimental phases. In fact, while the hippocampal theta ratio remained stable in the fast learners as a function of training, it decreased in the slow learners already during unpaired training. In addition, the presence of hippocampal theta activity enhanced the hippocampal model of the conditioned response (CR) and seemed to be beneficial for CR performance in terms of peak latency during conditioning, but did not have any effect when the animals showed asymptotic learning. Together with earlier findings, these results imply that the behavioral state in which hippocampal theta activity is absent is detrimental for learning, and that the behavioral state in which hippocampal theta activity dominates is beneficial for learning, at least before a well-learned state is achieved.
