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.     

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.     

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.     

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.     

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.     

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.     

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.     

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.     

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.     

Individual differences in 10‐month‐olds' performance on the A‐not‐B task

This study used the classical A‐not‐B task (Piaget, 1954 ) to explore individual differences in cognitive flexibility in 10‐month‐old infants by: (1) examining how differences in search performance during A trials relate to search performance during B trials; (2) studying the relation between temperamental dimensions and A‐not‐B performance; and (3) investigating differences in search performance between looking and reaching responses within the same task. Forty infants were tested on a fixed‐design‐version of the A‐not‐B task, not allowing for training or individual adjustment, but instead eliciting additional search behaviors than the common correct responses in A trials and perseverative errors in B trials. Infants were also rated by their parents on the temperamental scales Activity level and Attention span. The main findings were: (1) performance on A trials affected B trial performance, with infants being more correct on A trials having more incorrect and less ‘no search’ responses on B trials; (2) activity level, but not attention span, was related to performance on the A‐not‐B task, with infants performing better on A trials having a lower activity level; and (3) there were a few differences in performance with regard to modality, indicating that responding correctly by looking may be less cognitively demanding than doing so by reaching. This study demonstrated that 10‐month‐olds show a wide variation of search behaviors on this A‐not‐B task, resulting in individual differences in performance. These differences are suggested to reflect variation in temperamental activity level as well as maturity of short term/working memory, inhibition and cognitive flexibility.     

Incipient adult personality: The NEO‐PI‐3 in middle‐school‐aged children

This study administered the NEO Personality Inventory‐3 (NEO‐PI‐3), a more readable version of an adult measure of the Five‐Factor Model, to 449 boys and girls aged 12 and 13, who described themselves or a peer. Analyses of readability, reliability, factor structure, and convergent and discriminant validity suggested that the NEO‐PI‐3 can be appropriately used in this age group. Personality traits in children of this age closely resemble in structure and functioning the traits of older adolescents and adults. Most gender differences known from studies of adults are found in this age group, and mean levels show continuity with older groups. The NEO‐PI‐3 appears to be a useful instrument for research, and potentially for clinical applications, in middle‐school‐aged children.     

Self‐Compassion,Self‐Esteem,and Well‐Being

This article focuses on the construct of self‐compassion and how it differs from self‐esteem. First, it discusses the fact that while self‐esteem is related to psychological well‐being, the pursuit of high self‐esteem can be problematic. Next it presents another way to feel good about oneself: self‐compassion. Self‐compassion entails treating oneself with kindness, recognizing one’s shared humanity, and being mindful when considering negative aspects of oneself. Finally, this article suggests that self‐compassion may offer similar mental health benefits as self‐esteem, but with fewer downsides. Research is presented which shows that self‐compassion provides greater emotional resilience and stability than self‐esteem, but involves less self‐evaluation, ego‐defensiveness, and self‐enhancement than self‐esteem. Whereas self‐esteem entails evaluating oneself positively and often involves the need to be special and above average, self‐compassion does not entail self‐evaluation or comparisons with others. Rather, it is a kind, connected, and clear‐sighted way of relating to ourselves even in instances of failure, perceived inadequacy, and imperfection.     

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.
