Two‐year‐olds’ understanding of self‐symbols

This study investigated 48 2.5‐year‐olds’ ability to map from their own body to a two‐dimensional self‐representation and also examined relations between parents’ talk about body representations and their children's understanding of self‐symbols. Children participated in two dual‐representation tasks in which they were asked to match body parts between a symbol and its referent. In one task, they used a self‐symbol and in the other they used a symbol for a doll. Participants were also read a book about body parts by a parent. As a group, children found the self‐symbol task more difficult than the doll‐task; however, those whose parents explicitly pointed out the relation between their children's bodies and the symbols in the book performed better on the self‐symbol task. The findings demonstrate that 2‐year‐old children have difficulty comprehending a self‐symbol, even when it is two‐dimensional and approximately the same size as them, and suggest that parents’ talk about self‐symbols may facilitate their understanding.     

Time‐of‐day variation of visuo‐spatial attention

Time‐of‐day variation of visuo‐spatial attention in relation to body temperature and subjective arousal was assessed. At five different times of day, alertness, covert, and overt orienting of attention were assessed in fifteen healthy subjects. Based on previous studies reporting a tight coupling of alerting and orienting the present study investigates potential attentional asymmetries induced by diurnal variations of arousal. Both covert and overt orienting of attention improved in the course of the day. However, no asymmetries between left and right visual hemifields could be detected. Covert orienting additionally covaried with body temperature, indicating a quite close relation between the attentional arousal and orienting system. Conversely, overt orienting only improved due to repeated testing but did not correlate with body temperature suggesting a partial independence of both modes of attentional orienting. It can be assumed that due to limited diurnal variations of arousal in the participants and practice effects caused by repeated testing, no attentional asymmetries could be provoked.     

ON THE WHAT‐IT‐IS‐LIKE‐NESS OF EXPERIENCE

It is common for philosophers to hold that experience can be characterized in a basic way as being something it is like for someone to undergo. In the paper it is argued that when this slogan is examined it is in some respects trivial and in others mistaken. It is concluded that the slogan should be abandoned.     

The role of signals in two variations of differential‐reinforcement‐of‐low‐rate procedures

Differential‐reinforcement‐of‐low‐rate (DRL) schedules are used to decrease the overall rate of, but not eliminate, a target response. Two variations of DRL, spaced‐responding and full‐session, exist. Preliminary comparative analyses suggest that the two schedules function differently when unsignaled. We compared response rates under these two DRL variations with and without signals. In Experiment 1, five preschool students played a game in which points were earned under DRL schedules. In some sessions, a stimulus signaled when responses would be reinforced (S+) or not reinforced (S‐). In others, only an S‐ was present. Signals (S+/S‐) facilitated and maintained responding in both types of DRL schedules. In Experiment 2, we modified the signals with five different preschoolers. Instead of an S‐ only, we did not present any signals. Elimination and high variability of the target response were observed with the S‐ only and absence of S+/S‐, respectively. Signaled DRL schedules are recommended for application.     

Speech‐perception‐in‐noise deficits in dyslexia

Speech perception deficits in developmental dyslexia were investigated in quiet and various noise conditions. Dyslexics exhibited clear speech perception deficits in noise but not in silence. Place‐of‐articulation was more affected than voicing or manner‐of‐articulation. Speech‐perception‐in‐noise deficits persisted when performance of dyslexics was compared to that of much younger children matched on reading age, underscoring the fundamental nature of speech‐perception‐in‐noise deficits. The deficits were not due to poor spectral or temporal resolution because dyslexics exhibited normal ‘masking release’ effects (i.e. better performance in fluctuating than in stationary noise). Moreover, speech‐perception‐in‐noise predicted significant unique variance in reading even after controlling for low‐level auditory, attentional, speech output, short‐term memory and phonological awareness processes. Finally, the presence of external noise did not seem to be a necessary condition for speech perception deficits to occur because similar deficits were obtained when speech was degraded by eliminating temporal fine‐structure cues without using external noise. In conclusion, the core deficit of dyslexics seems to be a lack of speech robustness in the presence of external or internal noise.     

GTIDHNIHS: I knew‐it‐all‐along

Individuals who do insight problems are highly susceptible to hindsight bias. Two sets of studies assessed the impact of hindsight consequences on participants' judgements about anagram difficulty and specific factors for performance. In the first set, hindsight participants underestimated anagram difficulty relative to participants with task experience (worksight). Also, supportive evidence revealed that hindsight consequences were related to self‐perceptions of confidence, ability, performance satisfaction, and subsequent performance expectations. In the second, two different hindsight techniques differentially impacted the participant's assessment of anagram difficulty. When comparing hindsight participants with and without worksight experience, the latter judged the anagrams to be easier. It is appropriate to examine further the cognitive and motivational consequences of hindsight bias in achievement situations. Copyright © 2001 John Wiley & Sons, Ltd.     

Multidimensionality of Right‐Wing Authoritarian Attitudes: Authoritarianism‐Conservatism‐Traditionalism

Traditionally Right‐Wing Authoritarianism (RWA) has been seen as a unidimensional construct. Recently, however, researchers have begun to measure three distinct RWA dimensions (Feldman, 2003; Funke, 2005; Van Hiel, Cornelis, Roets, & De Clercq, 2006). One of these new multidimensional RWA approaches has conceptualized these three dimensions as Authoritarianism, Conservatism, and Traditionalism (ACT), which are viewed as expressions of basic social values or motivational goals that represent different, though related, strategies for attaining collective security at the expense of individual autonomy. Findings are reported from two studies to assess the validity and predictive utility of the multidimensional ACT approach. First, a direct cross‐national comparison showed that the three ACT dimensions were reliable and factorially distinct and demonstrated the measurement invariance of the three latent constructs across Serbian and NZ (New Zealand) samples. The three ACT dimensions predicted self‐reported behavior differentially in both samples, and a comparison of latent means showed the Serbian sample higher than the NZ sample on the ACT dimensions of Authoritarianism and Traditionalism but markedly lower on Conservatism. Second, a reanalysis of previously collected NZ data showed that the three ACT scales differentially predicted three dimensions of generalized prejudice in a theoretically meaningful manner. These findings underline the importance of studying ideological attitudes, such as RWA, multidimensionally.     

Goal‐Proximity Decision‐Making

Reinforcement learning (RL) models of decision‐making cannot account for human decisions in the absence of prior reward or punishment. We propose a mechanism for choosing among available options based on goal‐option association strengths, where association strengths between objects represent previously experienced object proximity. The proposed mechanism, Goal‐Proximity Decision‐making (GPD), is implemented within the ACT‐R cognitive framework. GPD is found to be more efficient than RL in three maze‐navigation simulations. GPD advantages over RL seem to grow as task difficulty is increased. An experiment is presented where participants are asked to make choices in the absence of prior reward. GPD captures human performance in this experiment better than RL.     

Fourteen‐month‐old infants learn similar‐sounding words

Can infants, in the very first stages of word learning, use their perceptual sensitivity to the phonetics of speech while learning words? Research to date suggests that infants of 14 months cannot learn two similar‐sounding words unless there is substantial contextual support. The current experiment advances our understanding of this failure by testing whether the source of infants’ difficulty lies in the learning or testing phase. Infants were taught to associate two similar‐sounding words with two different objects, and tested using a visual choice method rather than the standard Switch task. The results reveal that 14‐month‐olds are capable of learning and mapping two similar‐sounding labels; they can apply phonetic detail in new words. The findings are discussed in relation to infants’ concurrent failure, and the developmental transition to success, in the Switch task.     

Knowledge‐lies re‐examined

Sorensen says that my assertion that p is a knowledge‐lie if it is meant to undermine your justification for believing truly that ～p, not to make you believe that p and that, therefore, knowledge‐lies are not intended to deceive. It has been objected that they are meant to deceive because they are intended to make you more confident in a falsehood. In this paper, I propose a novel account according to which an assertion that p is a knowledge‐lie if it is intended not to provide evidence that p but to make you stop trusting all testimonies concerning whether p (in a room full of obvious liars, you will trust no one), which is how they undermine your testimonial knowledge. Because they are not intended to provide evidence that bears on the truth of p, they are not intended to make you more confident in a falsehood; therefore, knowledge‐lies are not intended to deceive. This makes them a problem for the traditional account, which takes the intention to deceive as necessary for lying, and an interesting example of Kant's idea that allowing lies whenever one feels like it would bring it about that statements in general are not believed.     

A Cross‐Cultural Exploration of Perceptions of Altruism of Counselors‐in‐Training

This study explored altruistic development as perceived by counselors‐in‐training from diverse cultures. Twenty‐two counselors‐in‐training from 4 countries participated in semistructured interviews about altruism. Using consensual qualitative research methodology, the authors identified 6 domains: biological, cognitive, social learning, religious/spiritual, counseling, and empathy. Findings and implications for counselor education are discussed.     

Attentional Predictors of 5‐month‐olds' Performance on a Looking A‐not‐B Task

In the first year of life, the ability to search for hidden objects is an indicator of object permanence and, when multiple locations are involved, executive function (i.e. inhibition, cognitive flexibility and working memory). The current study was designed to examine attentional predictors of search in 5‐month‐old infants (as measured by the looking A‐not‐B task), and whether levels of maternal education moderated the effect of the predictors. Specifically, in a separate task, the infants were shown a unique puppet, and we measured the percentage of time attending to the puppet, as well as the length of the longest look (i.e., peak fixation) directed towards the puppet. Across the entire sample (N = 390), the percentage of time attending to the puppet was positively related to performance on the visual A‐not‐B task. However, for infants whose mothers had not completed college, having a shorter peak looking time (after controlling for percentage of time) was also a predictor of visual A‐not‐B performance. The role of attention, peak fixation and maternal education in visual search is discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

NEO‐MEINONGIAN NEO‐RUSSELLIANS

Neo‐Russellianism, which incorporates both Millianism (with regard to proper names) and the thesis of singular Russellian propositions, has widely been defended after the publication of Kripke's Naming and Necessity. The view, however, encounters various problems regarding empty names, names that do not have semantic referents. Nathan Salmon and Scott Soames have defended neo‐Russellianism against such problems in a novel way; to account for various intuitions of competent and rational speakers regarding utterances of sentences containing empty names, Salmon and Soames appeal neither to entities similar to Fregean senses, e.g. propositional guises or modes of presentation, nor to Gricean implicatures. In this paper, however, I argue that their view slips into neo‐Meinongianism; it is committed to nonexistent objects, assigns various properties to them, and allows quantifiers range over such entities. This, I conclude, makes Salmon and Soames' view less appealing, if not implausible.     

Hierarchy of interactive functions in father‐mother‐baby three‐way games

In developmental research, the family has mainly been studied through dyadic interaction. Three‐way interactions have received less attention, partly because of their complexity. This difficulty may be overcome by distinguishing between four hierarchically embedded functions in three‐way interactions: (1) participation (inclusion of all participants), (2) organization (partners keeping to their roles), (3) focalization (sharing a common focus) and (4) affective contact (being in tune). We document this hierarchical model on a sample of 80 families observed in the Lausanne Trilogue Play situation across four different sites. Hierarchy between functions was demonstrated by means of Guttman scalability coefficient. Given the importance of the child's development in a threesome, the pertinence of this model for family assessment is discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Neural markers of subordinate‐level categorization in 6‐ to 7‐month‐old infants

Subordinate‐level category‐learning processes in infants were investigated with ERP and looking‐time measures. ERPs were recorded while 6‐ to 7‐month‐olds were presented with Saint Bernard images during familiarization, followed by novel Saint Bernards interspersed with Beagles during test. In addition, infant looking times were measured during a paired‐preference test (novel Saint Bernard vs. novel Beagle) conducted at the conclusion of ERP recording. Slow wave activity corresponded with learning a familiarized category at the subordinate and basic levels, whereas Negative central (Nc) and P400 components were linked with novel category preference. The results provide the first evidence identifying the neural markers of subordinate‐level categorization observed in looking‐time tasks conducted with infants. Moreover, when considered in conjunction with prior research investigating the neural markers of basic‐level categorization in infants, the findings indicate that (1) slow wave and Nc components of infant ERP waveforms are general markers for processes of category learning on the one hand and novel category preference on the other, (2) novel category preference for a contrast category at the basic and subordinate levels have the Nc component in common, but novel category preference at the subordinate level is accompanied by an additional P400 component, a finding in keeping with the notion that subordinate‐level categorization is governed by mechanisms supplementary to those underlying basic‐level categorization, and (3) slow wave activity associated with subordinate‐level learning followed that associated with basic‐level learning by approximately 200 ms, a result in accord with a coarse‐to‐fine scheme for the emergence of category partitioning.
