A cognitive-linguistic intervention model for mother-infant Pairs: Birth-to-three

There is a challenge to develop an educational technology which promotes cognitive and linguistic competency among children of the poor. Researchers who have studied early interactions between mother and child and service deliverers who have implemented parenting programs recognize the link between cognitive and language development. The focus of this paper is a curriculum model which includes both areas of development. The interactive behaviors of mother and child during three successive stages of the child's development (0–9 months, 9–18 months, and 18–36 months) from the matrix of the cognitive-linguistic intervention model.     

Leibniz-linked Pairs of Deductive Systems

A pair of deductive systems (S,S??) is Leibniz-linked when S?? is an extension of S and on every algebra there is a map sending each filter of S to a filter of S?? with the same Leibniz congruence. We study this generalization to arbitrary deductive systems of the notion of the strong version of a protoalgebraic deductive system, studied in earlier papers, and of some results recently found for particular non-protoalgebraic deductive systems. The necessary examples and counterexamples found in the literature are described.     

可数图灵理想的恰对和一致上界

一个（图灵）理想,是满足两个封闭条件的图灵度集合：向下封闭;任意,中一对图灵度的上确界也在,中。可数理想不仅在图灵度整体性质的研究中有着重要意义,而且在对哥德尔可构成集合L精细结构的早期研究中也发挥过重要作用。研究可数理想的两个重要概念是：恰对和一致上界。借助这两个概念,我们可以将可数理想简化为一个（一致上界）或者一对（恰对）图灵度。通过前人的研究,我们可以发现这两个概念是紧密相连的,同时我们也可以对它们的关系提出进一步的问题。在本文中,我们证明以下定理：任给一个可数理想I,都存在两个I的一致上界a0和a1,同时a0和a1构成,的一个恰对。此定理从正面回答了Lerman提出的关于算术图灵度构成的理想的一个问题。此定理的证明实际上是经过小心修改的、典型的恰对构造。我们在典型恰对构造的过程中,加入一些微妙的限制,使得形成恰对的两个图灵度a0和a1可以各自独立地在一定程度上用逼近的办法还原整个构造,从而分别给出可数理想I的一致枚举。在a0和a1分别的逼近中,我们引入了有穷损坏方法。本文的最后指出a0和a1的图灵跃迁的一些性质。     

An Improved Effect Size for Single-Case Research: Nonoverlap of All Pairs

Nonoverlap of All Pairs (NAP), an index of data overlap between phases in single-case research, is demonstrated and field tested with 200 published AB contrasts. NAP is a novel application of an established effect size known in various forms as Area Under the Curve (AUC), the Common Language Effect Size (CL), the Probability of Superiority (PS), the Dominance Statistic (DS), Mann-Whitney’s U, and Sommers D, among others. NAP was compared with 3 other non-overlap-based indices: PND (percent of nonoverlapping data), PEM (percent of data points exceeding the median), and PAND (percent of all nonoverlapping data), as well as Pearson’s R². Five questions were addressed about NAP: (a) typical NAP values, (b) its ability to discriminate among typical single-case research results, (c) its power and precision (confidence interval width), (d) its correlation with the established effect size index, R², and (e) its relationship with visual judgments. Results were positive, the new index equaling or outperforming the other overlap indices on most criteria.     

Detecting Deceit in Pairs of Children1

This study examined adults’ ability to distinguish between truthful and deceptive pairs of children. Adult observers (N = 88) judged the veracity of one of 22 truthful or deceptive pairs of children (12–13 years). The children were interviewed separately about their real or imagined encounters with an unknown man. Analyses showed that the overall accuracy was 62.5%; significantly better than chance level of 50%. Deception detection accuracy was higher when watching both pair members than when watching one child. The analysis of self‐reported cues to deception given by observers showed that the consistency between the children's statements was the most frequent cue. An analysis of the actual consistency of children's statements showed significantly more contradictions in the deceptive statements.     

Two Pairs of Conflicting Motives in Decision Making

A concept is proposed that decision making consists of resolving two conflicts. One of them is between the desire to make an accurate decision and the desire to minimize the effort of making a choice. The second conflict is between the desire to make an accurate decision and the desire that this decision is distinct. To operationalize basic motives involved in decision making, as assumed in the model, a new process tracing technique has been developed. Using this technique, three experiments were performed to test the predictions of the model. The experiments supported the predictions concerning the conflict between accuracy and distinctness. Similarity of choice alternative and decision importance appeared to affect the way the conflict between accuracy and distinctiveness is solved. An alternative explanation of the results obtained and perspectives of further research are discussed.     

Influence of Value on Spatial Balance of Color Pairs

The spatial balance of the component colors is an important element of color harmony in a design. Munsell (1905) suggested that the area of each color in a composition be inversely proportional to the product of the color's chroma and value. Moon and Spencer (1944) proposed that both chroma and value contribute to spatial balance, but the dominant factor is the contrast of a color with the background or with the adaptation point of the eye. The purpose of the present study was to investigate the predictive power of these two rules for hues of equal chroma, varying in value. The stimuli were presented on three different achromatic backgrounds, and both complementary and adjacent pairs of hues were used. When two colors differed in value, subjects tended to avoid equal areas. With black or white backgrounds subjects seemed to prefer larger areas of the color whose value was nearer that of the background, but with a gray background, their choice was either a narrow band of light or of dark color. These findings fail to support either the Munsell or the Moon and Spencer models.     

Cross‐Situational Learning of Minimal Word Pairs

Cross‐situational statistical learning of words involves tracking co‐occurrences of auditory words and objects across time to infer word‐referent mappings. Previous research has demonstrated that learners can infer referents across sets of very phonologically distinct words (e.g., WUG, DAX), but it remains unknown whether learners can encode fine phonological differences during cross‐situational statistical learning. This study examined learners’ cross‐situational statistical learning of minimal pairs that differed on one consonant segment (e.g., BON–TON), minimal pairs that differed on one vowel segment (e.g., DEET–DIT), and non‐minimal pairs that differed on two or three segments (e.g., BON–DEET). Learners performed above chance for all pairs, but performed worse on vowel minimal pairs than on consonant minimal pairs or non‐minimal pairs. These findings demonstrate that learners can encode fine phonetic detail while tracking word‐referent co‐occurrence probabilities, but they suggest that phonological encoding may be weaker for vowels than for consonants.     

Linking associative and serial list memory: Pairs versus triples

Paired associates and serial list memory are typically investigated separately. An "isolation principle" (J. B. Caplan, 2005) was proposed to explain behavior in both paradigms by using a single model, in which serial list and paired associates memory differ only in how isolated pairs of items are from interference from other studied items. In the present study, 2 experiments identify a critical dissociation between the 2 paradigms, challenging this unified account. Specifically, forward and backward probes were highly correlated for pairs and less so for short lists (triples). The authors asked whether the isolation principle could quantitatively accommodate this type of dissociation. A simulation confirmed that a single model incorporating the isolation principle can adequately explain this and other dissociations, supporting the common processes view.     

中医科学与中医文化有关问题的思考

对中医文化属性与科学属性的片面认识及相关内容归属的混乱,导致了一些重大中医科研项目的选题错误。预设附着于传统文化外衣下的专业概念、专业理论的科学真理性所进行的实证研究不可能获得预期结果。中医学的文化研究应当梳理出其核心价值体系,中医学的现代化研究应当与这一核心价值体系相统一。     

Various relationships between predatory dominance and aggressive behavior in Pairs of cats

The experiments were performed on adult male cats selected initially as good mousekillers. Cats were tested in pairs and each pair was introduced separately to the experimental compartment. The attitude toward the partner before and during the predatory competition test as well as superiority in catching and killing the mice, considered as an index of dominance, were registered. In the course of experiment five types of relations between the predatory dominance and aggressive behavior were observed. The concept of dominance as an outcome of several factors was discussed. It was concluded that predatory dominance is not based exclusively on aggressive mechanisms, as it may be formed and sustained without overt aggression.     

Pairs of Latin squares that produce digram-balanced Greco-Latin designs: A BASIC program

It is possible to create pairs of Latin squares that are digram balanced (in other words, that counterbalance immediate sequential effects) in a Greco-Latin design. A behavioral researcher can use these squares to design an efficient, well-balanced study without relying on chance. Researchers can apply these squares to any experiment in which they must pair conditions with different stimuli in a within-subject design. For experiments with a large number of conditions, however, the procedure is very time-consuming if done manually. A BASIC program is described that generates the correct pairs of squares for experiments with as many as 80 conditions.     

Gender-Typed Toy Play in Dizygotic Twin Pairs: A Test of Hormone Transfer Theory

Hormone transfer theory predicts thatopposite-sex twins will be affected in utero by thehormones their twins produce. This study examines theprediction that opposite-sex dizygotic twins should showless stereotyped toy play than same-sex dizygotictwins should show less stereotyped toy play thansame-sex dizygotic twins as a result of exposure toopposite-sex hormones in utero. Participants in thisstudy included 32 male-female dizygotic twin pairs,27 female-female pairs, and 24 male-male pairs. Allranged in age from 7 to 12 years and were primarilyCaucasian and middle class. Differences in the amount of time children played with feminine,masculine, and neutral stereotyped toys during free playwere examined. Results did not support hormone transfertheory. Girls played with feminine toys more than boys and boys played with masculine toys morethan girls, but there were no significant differencesbetween children with opposite- vs. same-sextwins.     

Now You Hear It: Fourteen-Month-Olds Succeed at Learning Minimal Pairs in Stressed Syllables

We examined whether 14-month-olds learn the mapping between a novel word and object in an associative-learning task when the forms differ minimally in only one segment where the crucial difference occurs in a stressed syllable. Fifty infants were presented with novel word–object pairings. Infants in one group heard the minimal difference in an initially stressed syllable, and the other group heard the minimal difference in a medially stressed syllable. Only those infants who were taught the medially stressed minimal pair detected a mismatch in the word–object pairing. These results demonstrate that 14-month-olds can succeed at minimal pair word learning when the critical information is presented in a stressed syllable, but importantly, only when particular acoustic cues are highlighted by syllable position—in this case, the medial position.
