This study continues an investigation of how spherical units, compared to cubical units, can facilitate students' units-locating and organizing units in composites. We analyze how Norwegian grade 3 students enumerate 3D arrays with cubical and spherical units. Our results show how spherical units can act as perceptual clues that facilitate…

Contemporary comprehensive mathematics teaching material covering whole courses has developed substantially from the early versions that roughly were 'books as pdf' with some complementary online material. In teaching materials that are offered in online web portals (digital teaching platforms) a variety of dynamic and interactive elements can be…

Most psychological theories treat the features of objects as being fixed and immediately available to observers. However, novel objects have an infinite array of properties that could potentially be encoded as features, raising the question of how people learn which features to use in representing those objects. We focus on the effects of…

We explored infants' ability to recognize the canonical colors of daily objects, including two color-specific objects (human face and fruit) and a non-color-specific object (flower), by using a preferential looking technique. A total of 58 infants between 5 and 8 months of age were tested with a stimulus composed of two color pictures of an object…

In the present study, we investigate how spatial attention, driven by unisensory and multisensory cues, can bias the access of information into visuo-spatial working memory (VSWM). In a series of four experiments, we compared the effectiveness of spatially-nonpredictive visual, auditory, or audiovisual cues in capturing participants' spatial…

Can infants use interposition and line junction cues to infer three-dimensional (3D) structure? Previous work has shown that in a task that required 4-month-olds to discriminate between static two-dimensional (2D) pictures of possible and impossible cubes, infants exhibited a spontaneous preference for displays of the impossible cube but left open…

The authors report a newly identified intertrial priming phenomenon, within-dimension singleton priming, by which search for a target that happens to be a singleton on the current trial is faster when the target on the previous trial had also been a singleton on the same dimension rather than a nonsingleton. This effect was replicated in 6…

Attempts to determine whether the stimulus dimension to which infants respond is different in fixed-trial and infant-control methodologies. Infants 10 weeks of age were shown four facelike patterns differing along two dimensions: number of elements and extent to which elements were organized to resemble the human face. (Author/RH)

Results suggest that when the internal element of a compound stimulus is a highly preferred or salient stimulus, young infants will process information about its characteristics. (Author/DB)

Four-month-old infants' stimulus preferences were assessed using an operant paradigm with mobile reinforcers of different colors (blue, green). (Author/MP)

In an evaluation of the relation between dimensional salience and preschoolers' judgments of bigness, 3-year-old children were shown triads of rectangles and asked to select the "big" one. The biggest rectangle in each triad was neither the tallest nor the widest. (JMB)

An investigation of 4-month-old children's attention responses to pattern dimensions and orientations by comparing the duration of an infant's fixation to changes in the orientation and structural arrangement of a previously exposed pattern. (ED)

The relationship between discriminability of scaling stimuli and assessed dimensional dominance was investigated in three studies. Results indicated that kindergarten children bring to the experimental situation a dimensional preference even when the values of all dimensions present are of equal and known discriminability. (GO)

A series of experiments is described whose aim was to define certain of the effective dimensions of stimulation in the newborn's visual environment. (Author/JMB)

Eight sets of paired auditory and visual stimuli were constructed. Each member of the auditory pair was matched by one member of the visual pair (e.g., ascending "tone/up arrow"; descending "tone/down arrow"). Sixty-one infants with a mean age of 11.4 months were presented matching and unmatching stimuli; total fixation time…
