Turn everyday scenes into meaningful social inferencing practice with Inference Pics Lite. Choose a photo and guide clients to notice important details, connect the clues and explain the thinking behind their inferences. Created by a speech-language pathologist (SLP), Inference Pics Lite includes 14 high-quality photos, with 2 from each activity, plus built-in questions and hints to support learning. The full version of Inference Pics expands the experience with 350+ photos and the ability to add your own photos, questions and hints. SOCIAL INFERENCING MADE SIMPLE We make social inferences every day. We use facial expressions, body language, surroundings, and context to work out how someone might be feeling, what they could be thinking, or what may have happened. For some children, teenagers, and adults, noticing these clues and putting them together can be challenging. Inference Pics Lite provides a simple, structured way for speech-language pathologists, teachers, parents, and caregivers to work on social understanding, expressive language, and reasoning skills in speech therapy, education, or at home. SEE WHAT INFERENCE PICS LITE CAN DO • Get learners explaining their thinking, not just giving an answer. • Save prep time with ready-made inference questions, answers, and hints. • Draw directly on photos to circle or highlight important clues. • Show or hide possible answers to adjust the level of support. • Target emotions, perspective-taking, expressive language, and social reasoning. • Practice interpreting facial expressions, body language, and context. • Work with photos of real-life situations, not cartoons. • Create user profiles and track results. • No subscription and no Wi-Fi needed. LOOK. THINK. EXPLAIN. Each inference picture in Inference Pics has two inference prompts/questions. The first question varies depending on the chosen inference activity. For example, in the Conversations activity the user is asked "What are they saying? while in the Seasons activity the inference prompt is "What time of year is it? The second question in each inference activity is always “How can you tell?”. This allows the user to practice verbal expression and giving explanations. It also prompts the child or adult to explain what clues they found to enable them to make an inference. TRY ALL 7 SOCIAL INFERENCING ACTIVITIES FEELINGS - Understand emotions from facial expressions, body language, and context. JOBS - Work out someone’s job from visual clues. PLACES - Infer where someone might be. SEASONS - Identify the season or occasion from contextual clues. WHAT HAS HAPPENED? - Piece together the evidence to work out what happened.
