The importance of gestural communication: a study of human–dog communication using incongruent information

We assessed how water rescue dogs, which were equally accustomed to respond to gestural and verbal requests, weighted gestural versus verbal information when asked by their owner to perform an action. Dogs were asked to perform four different actions (“sit”, “lie down”, “stay”, “come”) providing them with a single source of information (in Phase 1, gestural, and in Phase 2, verbal) or with incongruent information (in Phase 3, gestural and verbal commands referred to two different actions). In Phases 1 and 2, we recorded the frequency of correct responses as 0 or 1, whereas in Phase 3, we computed a ‘preference index’ (percentage of gestural commands followed over the total commands responded). Results showed that dogs followed gestures significantly better than words when these two types of information were used separately. Females were more likely to respond to gestural than verbal commands and males responded to verbal commands significantly better than females. In the incongruent condition, when gestures and words simultaneously indicated two different actions, the dogs overall preferred to execute the action required by the gesture rather than that required verbally, except when the verbal command “come” was paired with the gestural command “stay” with the owner moving away from the dog. Our data suggest that in dogs accustomed to respond to both gestural and verbal requests, gestures are more salient than words. However, dogs’ responses appeared to be dependent also on the contextual situation: dogs’ motivation to maintain proximity with an owner who was moving away could have led them to make the more ‘convenient’ choices between the two incongruent instructions.

Mother-child verbal interchange: A descriptive study of young children's verbal behavior

The theoretical importance of the linguistic data available to the child in his natural environment has been increasingly emphasized in recent work on child language acquisition. This study sought to describe a portion of such data as contained in maternal verbal behavior and to analyze its influence on the child's usage of speech. The subjects were five 21-month-old children and their mothers. The mother-child verbal interchange was recorded during free-play situations carried out both at the subject's home and in a playroom. The interactive patterns of mother-child utterances were analyzed with regard to the kind and frequency of verbalizations, and the temporal intervals between them. Results showed that the temporal pattern of mother-child interchanges was characterized by significantly shorter pauses (<2 s) for mothers than for children. A variation in this pattern, consisting of pauses longer than 4 s, was associated with certain kinds of ongoing mother-child verbal behaviors. Thus mothers showed selectiveness, in varying degrees, in responding to the child's utterances, and their verbal responses had differential effects on the child's subsequent verbal performance. These effects were described as “initiating”, “maintaining”, or “ending” verbal chains, or else as “non-reacted” utternances. Moreover, the amount of verbalization by the children was positively correlated with the proportion of the mother's output that consisted of immediate responses to the child, and not with the total verbal output.     

“That man’s father is my father’s son”: The roles of structure,strategy, and working memory in solving convoluted verbal problems

Normative data (N=896) collected on solutions to the traditional reasoning problem “Brothers and sisters have I none,/That man’s father is my father’s son” was the platform for a set of experiments to investigate the roles of problem structure, subject strategy, and working memory in error making in a class of verbal problems. The normative data revealed that the modal, but incorrect response to the brothers and sisters problem was “himself,” whereas the correct response of “son” was given by only 17% of subjects for the traditional version above, rising to 40% for a reordered novel version. This problem’s structure, identified as adouble-modifier structure, was found to produce similar response patterns across a range of verbal problems. Results from (1) syntactical structure manipulations (e.g., “My father’s son is the father of that man”), and (2) efforts to teach subjects to use a linear strategy (a sequence of steps), interpreted within a framework of Just and Carpenter’s (1992) capacity theory of comprehension, suggested that working memory overload varies across within-structure modifications and subjects. Further-more, this overload may be compounded by subjects’ choices of strategy.     

Pictorial and verbal encoding in a short-term memory task

The present research attempted to manipulate the encoding modality, pictorial or verbal, of schematic faces with well-learned names by manipulating S’s expectations of the way the material was to be used. On every trial, a single name or face was presented, followed by another one; the S was asked to respond “same” if the stimuli had the same name, and “different” otherwise. The majority of second stimuli of any session was either names or faces. It was hypothesized that if S had encoded the first stimulus in the modality of the second, his judgment would be faster than if he had not appropriately encoded the first stimulus. Significantly slower reaction times were obtained to stimulus pairs where the second stimulus modality was infrequent. Further evidence that encoding of the first stimulus was in the frequent second stimulus modality comes from the finding that “different” responses were shorter when the stimuli differed on more than one attribute in the encoding (second stimulus) modality, regardless of the modality of the stimuli. Thus, evidence is presented that not only can verbal material be pictorially encoded (and vice versa), but that whether either verbal or pictorial material is verbally or pictorially encoded depends on S’s anticipation of what he is to do with the material.     

Pictorial depth perception: Tasks levels imposed by testing instruments

Attempts to devise verbal and non-verbal instruments for measuring pictorial depth perception that are different from Hudson's (1960) have resulted in different perceptual demands. Whereas this was recognized by the constructors of non-verbal tests, it was not by those who changed Hudson's question “Which is nearer to the man…?” to “Which is/looks nearer/farther to you… ?”. While the latter question tests simple perception (or interpretation of cues) of pictorial depth, the former tests comprehension of complex pictorial space relations arising from the depth perceived. A verbal instrument that had been devised for testing simple pictorial depth interpretation, equivalent to Jahoda and McGurk's (1974) non-verbal instrument, was tested on Grade 3 Shona children against the hypothesis that the terms “nearer” and “farther” have different lexical markings likely to affect subject's responses. No support was found for the hypothesis, but Opolot's (1976) Grade 3 findings were able to be explained.     

Das Traumgenerierungsmodell von Ulrich Moser und die Codierung von Traumprozessen

Under the conditions of sleeping, mental activity creates a psychic microworld “dream” experienced as the present, running predominantly in a pictorial and sensual way in a sequence of situations and sometimes containing verbal relations and cognitive processes. Together with Ilka von Zeppelin, Ulrich Moser has developed a model of the emergence of sleep dreams with the aim to reconstruct the dreaming process, which is normally concealed under the verbal structure of the dream report and to explain this sequence as the result of a cognitive affective regulatory process. In accordance with the theory of French, dreaming is seen as an attempt to cope in a simulative mode with unresolved neurotic conflicts and traumatic experiences. To make this process visible, the authors developed a very differentiated model-guided coding system, a form of operationalization of the “dream work” that records and describes all cognitive elements and all interactive behavior in the dream. This analysis provides the formal and structural characteristics of the dream that precede every interpretation of content or biographical meaning. In this way, dream series in a single person, as well as dreams in different groups, can be objectively studied and compared. A presentation of the dream model is followed by an introduction into the basic principles of the coding system. This dream process coding and the interpretation based on it are demonstrated on a specimen dream. This dream is Freud’s “Dream of Irma’s injection”, which he selected himself to demonstrate his method of dream interpretation in Die Traumdeutung and which was also used by Erikson to illustrate his “configurational analysis”.     

Antecedent Selection: Comparing Simplified and Typical Verbal Antecedents for Children with Autism

This study measured the differential effects of simplified and typical verbal antecedents on acquisition of picture discriminations for four preschool children with autism. During baseline probes, participants emitted no correct selection responses to pictures of common stimuli during either simplified or typical verbal antecedent conditions. Using an adapted alternating treatments design during training, instructors presented a simplified verbal antecedent (i.e., “Give me car”) or a typical verbal antecedent (i.e., “One of these is a car. Which one is it?”), and differentially reinforced participants’ correct selection responses given the target picture and two non-targets. Results showed that one participant emitted more correct responses during simplified than typical verbal antecedent conditions, one participant emitted more correct responses during typical than simple verbal antecedent conditions, and there was no clear difference for the other two participants.     

Functional cerebral lateralization in subtypes of disabled readers

This study investigated the functional cortical organization of reading-disabled boys and age-matched normal readers. Subjects were initially classified according to E. Boder's (1971a. In B. Bateman (Ed.), Learning disorders. Seattle: Special Child Publications. Vol. 4.) distinction between dysphonetic children (who make nonphonetic, bizarre spelling errors), dyseidetic children (who make phonetically acceptable errors, but do not respond to some words as “wholes”), and children who display normal error patterns (who make phonetically acceptable errors and respond to words as “wholes”). It was hypothesized that different types of reading disability would be associated with different patterns of lateralized brain function. This proposal was examined by testing subjects on three experimental neuropsychological measures—hemispheric time-sharing, conjugate lateral eye movements, and tactile directional perception. Conjugate lateral eye movements were disregarded as the control subjects failed to show predicted asymmetries on this measure. The two other measures were considered valid and demonstrated atypical lateralization in the reading-disabled groups. Lateralization of verbal and/or spatial functiosn differed among the reading-disabled groups and an attempt was made to relate these atypical patterns to the type of reading difficulties presented.     

Non-verbal communication enables children’s coordination in a “Stag Hunt” game

This study assessed the role of non-verbal communication in 4-year-old children’s decisions to coordinate with others. During a “Stag Hunt” game, the child and an adult individually and continually collected low-value prizes (hares). Occasionally, an alternative option of collecting a high-value prize (stag) cooperatively with the adult arose, but entailed a risk: a lone attempt on this prize by either player would leave that player empty handed. Children coordinated with the adult to obtain the high-value prize more often when that adult made mutual eye contact and smiled at them than when she attended to the prizes only. This suggests that neither verbal nor gestural communication are necessary for coordination: Minimal, non-verbal communication enables children’s coordination with others towards joint goals.

Children’s strategy use when playing strategic games

Strategic games require reasoning about other people’s and one’s own beliefs or intentions. Although they have clear commonalities with psychological tests of theory of mind, they are not clearly related to theory of mind tests for children between 9 and 10 years of age “Flobbe et al. J Logic Language Inform 17(4):417–442 (2008)”. We studied children’s (5–12 years of age) individual differences in how they played a strategic game by analyzing the strategies that they applied in a zero, first, and second-order reasoning task. For the zero-order task, we found two subgroups with different accuracy levels. For the first-order task, subgroups of children applied different suboptimal strategies or an optimal strategy. For the second-order task only suboptimal strategies were present. Strategy use for all tasks was related to age. The 5- and 6-year old children were additionally tested on theory of mind understanding and executive functioning. Strategy-use in these children was related to working memory, but not to theory of mind after correction for age, verbal ability and general IQ.     

Graphics in psychology: Pictures,data, and especially concepts

Over the last 50 years, psychologists have included numerous graphics in their journals and textbooks. The textbooks have contained mostly pictures, whereas the journals have contained mostly data graphs. Surprisingly, conceptual graphs (such as a network chart of the relations among types of memory) have been very infrequent. There are two main reasons for this absence of conceptual graphs: a lack of awareness of the important role that they have played in the history of our discipline, and a lack of knowledge about how to make them. Four types of conceptual graphs are presented here: mathematical graphs (e.g., Fechner’s law), geometric models (e.g., Henning’s smell prism), networks (e.g., Atkinson and Shiffrin’s STM-LTM model), and EulerVenn graphs (e.g., Shiffrin and Schneider’s model of control and automatic processes). Suggestions are offered forheuristics that can be used to facilitate the perception of conceptual relations in these graphs. It is argued that appropriate conceptual graphs can help researchers and theorists communicate the “big picture” relevant to their ideas, can help educators more effectively communicate with students, and may help clinical psychologists communicate their ideas to clients better.     

Discussion

While in no way denying the interest of the study of “Theories of Mind”, the discussion tends to show that, in the tasks described in the papers, the development of abilities to process perceptual and verbal information is sufficient in itself to fully account for changes in observed responses. Whether the issue is false beliefs or the distinction between appearance and reality, children's behavior is highly dependent on their working memory span, their operational efficiency (action coordination) and their current state of knowledge. “Theories of Mind” emerge as indices of cognitive development. Their adaptive value is more problematical.

Caregivers’ Positive Emotional Expression and Children’s Psychological Functioning after Parental Loss

The death of a loved one, particularly a parent, has been identified as not only the most common, but also the most distressing form of adversity youth may experience in their lifetime. Surviving caregivers’ communication with their children may play a critical role in shaping bereaved children’s psychological functioning. However, few studies have examined the specific content (e.g., word usage) of caregivers’ verbal communication as a predictor of psychological functioning in bereaved youth. In a sample of 39 parentally-bereaved children and their surviving caregivers, we investigated whether the frequency of caregivers’ use of positive emotion words (e.g., “love”, “happy”, “hope”) during a reminiscing task about the deceased was associated with children’s psychological functioning and coping. In a cross-sectional analysis, we specifically examined whether these associations were moderated by the amount of time passed since children lost their parents. The Linguistic Inquiry and Word Count Program (LIWC) was used to code and evaluate the percentage of positive emotion words caregivers used during the discussion. When caregivers used more positive emotion words, children were less likely to experience depression, anxiety, and avoidant coping. Those associations were present for children who had experienced parental loss at least 105 days prior to the study.     

ATTENTION TRAINING: THE USE OF OVERCORRECTION AVOIDANCE TO INCREASE THE EYE CONTACT OF AUTISTIC AND RETARDED CHILDREN

A crucial first step in teaching and training the retarded and autistic is to develop and maintain eye contact with the therapist. Functional movement training (an overcorrection procedure) plus edibles and praise were compared with edibles and praise alone as a method of developing eye contact in three such children. In both conditions, the child was given food and praise when eye contact occurred within 5 sec of the therapist's verbal prompt: “Look at me.” Functional movement training avoidance plus edibles and praise produced about 90% attention for the three children, while edibles and praise alone were less effective (eye contact never exceeded 55%). Functional movement training avoidance combined with edibles and praise appears to be an effective method of teaching eye contact and possibly other forms of instruction-following to behaviorally disordered children who are not always responsive to positive consequences.     

Gender constancy: A methodological and theoretical analysis

Two widely used tests of gender constancy, one verbal and one perceptual, were given to 26 4-to-6-year-old children. Children were classified at different levels of gender constancy, depending on which test was used. These discrepant results were not accounted for by the differences in the way the tests presented (verbally or visually), nor by the tests' differing definitions of gender constancy. The majority of the children answered gender constancy questions as though they were referring to a “pretend,” as opposed to a “real,” situation; such responses decreased scores of gender constancy on both tests. The theoretical and methodological implications of children spontaneously adopting a pretend mode of responding are discussed.     

Parity and Comparability—a Concern Regarding Chang’s Chaining Argument

According to Ruth Chang the three standard positive value relations: “better than”, “worse than” and “equally good” do not fully exhaust the conceptual space for positive value relations. According to her, there is room for a fourth positive value relation, which she calls “parity”. Her argument for parity comes in three parts. First, she argues that there are items that are not related by the standard three value relations. Second, that these items are not incomparable, and third, that the phenomena she has focused on are not due to the vagueness of the comparative predicates (i.e., that it is indeterminate which of the standard value relations that holds). This paper focuses on the second part of the argument and an objection is presented. By assuming the Small Unidimensional Difference Principle, which is a key premise for the second part of the argument, Chang’s argument could be accused of begging the question. More so, by assuming this principle, the space for incomparability gets severely limited. If these worries are justified, then Chang’s argument for parity as a fourth form of comparability is unsuccessful.
